Aiming at correcting the severe chromatic aberration of the long focal lens, the traditional optical design often requires employing complex structure, introducing special dispersive glasses or even utilizing the hybrid refractive-diffractive imaging method. However, complex structure will bring several drawbacks such as large volume and heavy weight. Special glasses and refractive-diffractive hybrid imaging will greatly increase the cost, which hardly meets the needs of miniaturization and low cost of optical imaging module. Although image restoration algorithm is commonly used to optimize the image quality to a certain extent, the optical design and image restoration process are independent of each other. Therefore, it is difficult to ensure the high resolution of the image while realizing the light weight, small volume and low cost of the optical system simultaneously. Utilizing the computational imaging theory, a simple long-focus optical system design method based on the optical/image co-design is proposed and deomonstrated in this paper. On the basis of the idea of global optimization, the reported approach considers the two independent links of optical design and image restoration as a combination. The imaging quality requirements in the optical system design are relaxed at the front end, and the image restoration algorithm is used to remove the residual aberrations in the back end. This method can not only obtain the same or even higher imaging performance, but also reduce the complexity of the optical system.

This paper reports a design of a high magnification mid-wave infrared (MWIR) continuous zoom lens system that is compatible with a high-resolution focal plane array (FPA). The zoom lens design has been developed via a series of optimization processes, from a global search to look for potential design candidates, to different local optimization strategies to balance out optical aberrations between different zoom configurations, then comes a few minor adjustments in order to mitigate the negative effects that the optical system might encounter during its operation. By using these processes, an F/5.5 continuous zoom lens system with a magnification ratio of 22x that works with an SXGA (1280 x 1024) cooled detector having a pixel pitch of 15 μm has been successfully designed. This zoom lens system only makes use of two movable lenses to maintain its performance throughout the entire zoom range. With a maximum focal length of 1200 mm, this optical system plays a major role in extremely long range observation and surveillance applications.
本文报道了一种与高分辨率焦平面阵列(FPA)兼容的高放大倍数中波红外(MWIR)连续变焦镜头系统的设计。变焦镜头的设计经过了一系列的优化过程，从全局搜索寻找潜在的设计候选，到不同的局部优化策略来平衡不同变焦配置之间的光学像差，然后是一些小的调整，以减轻光学系统在运行过程中可能遇到的负面影响。利用这些工艺，成功设计了一种放大倍率为22倍的F/5.5连续变焦镜头系统，该系统可与像素间距为15 μm的SXGA (1280 x 1024)冷却探测器配合使用。这种变焦镜头系统只使用两个可移动的镜头，以保持其在整个变焦范围内的性能。该光学系统的最大焦距为1200毫米，在极远距离观测和监视应用中发挥重要作用。

Unlike the conventional design of aspheric shaping systems, in order to provide a laser source for applications such as multi-beam laser interference, which can maintain evenly distributed power over a large distance, the influence of shape parameter and aperture on long-distance propagation performance of Kepler refractive beam shaping system is studied. Current work describes the lens, designed automatically by using ZEMAX programming language (ZPL), and simulations of Kepler refractive shaping systems of flattened Lorenz (FL) beams with different shape parameters and apertures.

Recently, more and more attention is paid to the multichannel optical system. They are often used in microscopy. Examples include metallographic microscopy, confocal microscopy, laser scanning microscopy, optical coherence tomography, and others. Usually, one channel of such systems is lighting, and the other is observation. Such systems usually do not pay attention to the uniformity of the divided light flux. Here it is important to illuminate the object and obtain an image, and if the illumination is insufficient, the luminous flux given by the source is increased. However, if both channels of the system are used for imaging (possibly with different characteristics), the uniformity of this splitting of the optical emission is an important part. Otherwise, we risk not getting the image we need in one of the channels. The paper presents the features of optical systems (lenses) that ensure uniform separation of optical emission. Examples of such optical systems are given.
