Abstract This study investigated the characteristics and location of the pigment layer of commercially available tinted contact lenses and evaluated ocular surface properties. The rub-off test and anterior segment Fourier-domain optical coherence tomography were used to analyze the pigment layer of the lenses. They also completed a rating questionnaire of subjective symptom perception after wearing. Among the four groups, there were significant differences in the ocular surface properties on day 3 (p < 0.05). Most of the ocular surface properties were significantly different between baseline and after being worn on day 1, day 3 and day 7 (p < 0.05), especially for tinted contact lenses with pigment layers on the lens surface. On initial wearing of the tinted contact lenses, contact between pigment layers on the surface of the lens and ocular tissues appeared to irritate the ocular surface more than non-pigment layers on the surface. Pigment-tinted soft contact lenses with lower oxygen permeability may cause worse ischemic signs on the ocular surface. However, the ocular surface adapted gradually and the symptoms decreased after wearing the tinted contact lens.

Abstract Wafer bonding is an attractive technology that can join homo/heterogeneous materials into one composite. It has a wide range of applications in the micro-electro-mechanical system (MEMS), integrated circuit, consumer and power electronics, micro/nanofluidics, etc. Since all devices on the same wafer are sealed and tested at wafer size, it brings lots of benefits compared with the component-level packaging, such as substantial savings in time, materials, and labor. In this review, we firstly introduce the low- and room-temperature Si bonding and their applications in MEMS fabrication. Subsequently, we present applications of the third-generation semiconductor bonding towards optoelectronics. Due to the research in the electro-optical modulation of lithium niobate (LiNbO3) has made revolutionary progress in recent years, we also show the bonding method towards single-crystal LiNbO3 thin-film fabrication. Finally, we set our sights on the bonding of infrared materials, which might be the next research hotspot for the emerging ultrasensitive sensors.

Abstract Advances in astronomy led to the demand for measuring the spectra of multiple night sky objects simultaneously. Some of these Multi-Object Spectrographs use robotic systems that position optical fibers in the focal plane of the observing telescope. These systems rely on precise fiber placement in order to collect the light spectra of faint stars and galaxies. Here, we present how to design, control, and operate micro SCARA-like robots to position optical fibers to micrometer precision. As an illustrative example, we show the design and performance results of the SDSS-V fiber positioner, which has been build for the Apache Point Observatory and the Las Campanas Observatory with 500 units for each telescope.

Abstract In recent years, electromagnetic characteristics of metamaterials has aroused great interest because of innovative fundamental understanding as well as promising potential applications in optics, semiconductors, imaging, and sensing. We survey the state-of-the-art of spatially reconfigurable metamaterials in which electromagnetic Lorentz, Coulomb, and Ampere forces, as well as optical signals and thermal stimulation can be dynamically changed their optical properties. Electro-mechanical and optical inputs change the amplitude, phase, polarization of incident electromagnetic wave, and optical response within these metamaterials, which can be driven by electric or optical signals. Based on a solid theoretical foundation, we review the most recent experimental works on reconfigurable metamaterials endowed with an active tuning characteristic. Additionally, we review the potential metamaterial applications that may inspire new research works and offer a comparison to other optoelectronic fields.

Abstract This paper proposes an intelligent approach (fuzzy logic) for the design of external-cavity semiconductor lasers (ECLs) for better disturbance rejection. As a kind of nonlinear optical system, ECL output frequency is difficult to be stabilized by conventional methods. The fuzzy logic algorithm is preferred for ECLs stabilization, which could update parameters automatically. Suddenability to reject nonlinear disturbances arch occur in the fuzzy logic systemduring operation, speed of operation and PID gains are alteredonline in accordance with the disturbances to reject. To showthe efficacy of the proposed method, a fuzzy logic ECL stabilization system is designed. The results prove that our method is effective and robust.

Abstract A transparent, conductive, smooth, and temperature sensitive thin films was fabricated and characterized in this paper. Silk fibroin could be processed into transparent thin films, which can act as ideal opto-electronic substrates. As pure silk fibroin film is nonconductive, ultra-long silver nanowires coating and platinum sputtering were used to strengthen its conductivity. Ultra-long nanowires were used to reduce the junctions between wires, and platinum was to improve the conductivity of the film. The new nanowire-metal-organic composite film possesses excellent conductivity and good transmittance. The composite films containing different silver nanowires exhibit conductivities of as low as 6.9 Ω/sq, and transmittance of 60–80% in the visible light range. The films also showed potentials in practical applications as their resistance is almost linearly temperature-dependent. It also can transfer power to electrical devices. The new composite films could be expected to function in wearable electronics or implantable devices and sensors.

Abstract Vein display device can significantly increase the success rate of intravenous injection. However, traditional vein display devices only contain near-infrared image information, which inevitably loses skin color information. In this article, a binocular microlens was fabricated by micro-fabrication technology. Then, a smart binocular microlens imaging system is set up. By this system, the near-infrared image with venous distribution and visible light image with actual skin color can be obtained simultaneously. In addition, an improved image fusing algorithm is proposed. The image fusing result shows that the venous details can be clearly shown and the background color of the hand also can be well preserved. Therefore, the proposed scheme can provide more real vein information. As the smart structure of the binocular microlens, the dual-bands microlens imaging system has the potential for miniaturization and could integrate with intelligent glasses for assisting intravenous injection.

Abstract In this paper, a rectangular magnetic fluid deformable mirror (MFDM) with dual-layer actuators is proposed, which is designed to improve the correction performance for full-order aberrations. Compared with the conventional adaptive optics system that uses two mirrors to configure as a woofer–tweeter system, the proposed MFDM combines the two mirrors into one by using a two-layer layout design of the actuators. Firstly, based on the governing equations of the magnetic fluid, derived from the principles of conservation of fluid mass and magnetic field, the dynamics model of surface deflection of the MFDM is analyzed in Cartesian coordinates under the boundary conditions of the magnetic field and the kinematic conditions of magnetic fluid. Then, the analytical solutions of the surface movement of the mirror subject to the applied currents in the electromagnetic coils are obtained by properly separating the variables with truncated model numbers. Finally, the experimental results based on a fabricated prototype square MFDM show the effectiveness of modeling and the correction performance of the mirror for the full-order aberrations.

Abstract Marginal changes in geometrical dimensions due to temperature changes affect the performance of optical instruments. Highly dimensionally stable materials can minimize these effects since they offer low coefficients of thermal expansion (CTE). Our dilatometer, based on heterodyne interferometry, is able to determine the CTE in range. Here, we present the improved interferometer performance using angular measurements via differential wavefront sensing to correct for tilt-to-length coupling. The setup was tested by measuring the CTE of a single-crystal silicon at 285 K. Results are in good agreement with the reported values and show a bias of less than 1%.

Abstract We present a novel method to accurately measure the flatness of a large flat. The method can be seen as a task-specific error correction of the laser tracker. Laser trackers are positioned at two specific measuring stations and measure the coordinates of the same sample points. The angular errors of the primary laser tracker are compensated with constraint information provided by an additional laser tracker. Using this method, we measure the flatness of a 4.5 m flat. The flatness measurement uncertainty is 1.4 µm in rms (root mean square).
