Referenceless phase holography (RELPH) is a lensless holographic method that generates the full (amplitude and phase) optical field if intensity and phase distributions of this field in one plane are given as numerical data. It is based on the interference of two pure phase fields that are produced by reflection of two mutually coherent plane waves at two phase modulating spatial light modulators (SLM). The optical field of any real or artificial three-dimensional (3D) scene can be displayed. This means that referenceless phase holography is a promising method for future 3D television or 3D cinema as well as for interferometric metrology. We introduce the theory of RELPH, possible technical realizations, and discuss the numerics. The possibilities and problems in calculating the diffraction fields of given 3D scenes are worked out, modifications of the algorithms are presented. Experiments are shown, not only proving the practicability of RELPH, but also confirming the various 3D cues, such as depth of field, occlusion, and parallax. Two approaches to multicolor display are presented and experimentally verified. The benefits and advantages of RELPH are outlined, open problems and necessary technological developments as well as possibilities and future prospects are discussed.

Digital lensless holographic microscopy (DLHM) allows the design of cost-effective systems using off-the-shelf materials, making this type of lensless microscope accessible to many users worldwide. However, these materials may have a limited optomechanical performance that is aggravated due to the sought compactness and the intended cost-effective manufacturing process. This problem particularly affects the illumination source, which is of critical importance for DLHM, as it defines the optical performance of the microscope. While recent reports show that the required point source can be built from a low-cost laser diode coupled to an also low-cost aspheric lens, the resulting illumination has a distorted wavefront that limits the performance of the microscope. A simple homemade setup to correct the distortion of such illumination source and its integration into a compact, cost-effective, DIY, and open-source-certifiable digital lensless holographic microscope, is presented. The distortion-corrected DLHM is validated by imaging calibrated test targets and biological samples, achieving a 12-fold extension on the distortion-free magnification range of previous designs and a doubling of the effective spatial resolution without significant increments in its overall cost.

Speckle metrology techniques utilize the phenomenon of speckle patterns for various measurement applications. Speckle pattern interferometry and speckle shearography are the widely used speckle metrological techniques in diverse fields. In speckle interferometry, the phase map embedded in the speckle pattern fringes is directly proportional to the displacement; however, in speckle shearography, it is related directly to displacement derivative. We aim to explore the relationship between the extracted phase derivative from speckle fringe pattern and the phase from their corresponding shearing fringes along the x and y directions. A speckle fringe pattern and the sheared fringes along the x and y directions are numerically generated. From speckle fringe pattern, the phase derivatives along the x and y directions are extracted by using the Riesz transform algorithm, whereas from the shearing fringes, the phase distribution is extracted by using monogenic signal. The similarity between the phase derivate distribution from speckle fringe pattern and phase distribution from sheared fringe is quantitatively evaluated by using image quality index. Furthermore, application experimental data are also presented.

A multi-view occlusion removal method for digital lensless holographic microscopy (DLHM) is presented. Multiple DLHM holograms, whose individual reconstructions show occluded or partially occluded sample details, are recorded for different sample placements at its plane. A coordinated addition of the multiple DLHM recordings produces a composite hologram whose reconstruction allows the removal of the occlusions for a given imaging plane while increasing the reconstructed field of view. A theoretical model supports the method and its feasibility is tested with phase bio- and non-bio samples.

We introduce a lensless long wave infrared (LWIR) sensing system, utilizing double-random phase encoding. The employment of thin random phase encoding elements eliminates the need for traditional optical lenses. For object classification, convolutional neural network is used to process the speckle patterns produced by the random phase encoding, thus avoiding the reconstruction problem associated with lensless imaging. This approach is attractive for applications demanding compactness and cost-efficiency for LWIR systems. Experiments are provided to illustrate the proposed system. Our results demonstrate that this system competes well with conventional lensed LWIR imaging methods in a binary classification task under noisy conditions, where noise is not known a priori. To the best of our knowledge, this is the first report on such approaches in the LWIR domain.

Digital holography allows for the recording and reconstruction of three-dimensional images using interference and diffraction principles. The propagation of light from the hologram plane to the reconstruction plane is a crucial step, often achieved through Fresnel propagation, a method that inherently transforms the reconstructed pixel pitch to provide diffraction-limited imaging. However, the accuracy of this method is limited by the Fresnel approximation, especially in applications such as digital holographic microscopy. We present a simple method that significantly improves the accuracy of the Fresnel approximation by incorporating higher orders of the binomial approximation. We validate the effectiveness of our approach through high numerical aperture simulations and experimental results, demonstrating superior sub-micron resolution and reduced distortions compared with standard Fresnel propagation.

Scatterometry has been put into practical use for microstructure measurement of ultra-large-scale integration due to its high process compatibility. On the other hand, its application has been limited to periodic structures. By applying this method to isolated systems and using hard X-rays, it may be possible to significantly exceed a resolution of 10 nm, which is the limit of conventional optical measurement. We demonstrate the feasibility of this measurement by rigorous calculations. For this purpose, we measured the intensity of specular reflection and noise at the beamline of hard X-ray radiation. The virtual target is a 15-nm-wide lattice. The signal-to-noise ratio is low enough for a lattice with a period of 25 nm but 10 times higher for an isolated lattice.
散射测量法因其高度的工艺兼容性，已被实际用于超大规模集成的微观结构测量。另一方面，其应用仅限于周期性结构。通过将这种方法应用于孤立系统并使用硬 X 射线，有可能大大超过 10 纳米的分辨率，而这正是传统光学测量的极限。我们通过严格的计算证明了这种测量方法的可行性。为此，我们测量了硬 X 射线辐射光束线的镜面反射强度和噪声。虚拟目标是一个 15 纳米宽的晶格。对于周期为 25 纳米的晶格，信噪比足够低，但对于孤立晶格，信噪比则高出 10 倍。

Optics is an excellent complement to undergraduate study in fields such as mechanical, electrical, or biomedical engineering. Applications in those disciplines are also a great motivation for deeper learning in optics. One area in particular where optics and engineering intersect that is worthy of more attention is three-dimensional (3D) printing (3DP). I describe how optics concepts relevant to 3DP enhance the usual introductory discussion as well as how 3DP can be beneficial to the humbly stocked optics lab. The work concludes with some practical examples of capabilities that have been made possible in our instructional labs through 3DP.

Optics and photonics have become integral components of undergraduate and postgraduate curricula due to their extensive applications in physics, biology, and engineering, particularly in fields such as sensing and communication. Diffraction and interference phenomena are building blocks for understanding principles of optics and photonics based technologies. As a result, these concepts are taught to students at various educational levels in colleges and universities. However, many students currently face challenges in grasping the fundamental principles of light diffraction and interference. To address this issue, there is a need for an experimental setup that can effectively and visually explain these principles to students. We present a single-beam experimental setup. This setup is well suited for conducting a range of experiments related to the diffraction and interference of light. Through the utilization of this setup, we are able to showcase the experiments involving diffraction patterns produced by circular apertures, knife-edge diffraction, single slit, wire diffraction, as well as intriguing phenomena, such as the Poisson spot and spatial frequency filtering.

Public educational outreach is critical for introducing students to the field of optics. Video-sharing platforms, including YouTube and TikTok, are powerful tools for introducing optics to young students, especially as video consumption rates continue to rise. The proliferation of short, casual videos shot vertically on a cell phone on these applications and other social media platforms has greatly reduced the barriers to entry for educating through video. This work will cover the strategies and tactics used by Edmund Optics in recent years to establish and rapidly scale up a video-based outreach program that now reaches up to 13 million views per month. While this scale may at first seem unattainable, short-form video on social media provides a low-cost, low-time-requirement method for achieving this level of reach. In addition to practical guidance for educational video creation, the benefits of such an effort to the company or institution who sponsors it and tips to get buy-in from organizational leadership will be shared. A digital video-based optics outreach program can serve as the foundation for a larger outreach effort that develops the future photonics workforce.
