Optical analog computing has attracted extensive interest in image processing and optical engineering in recent decades. Here, we propose a reflective optical analog computing system based on a cholesteric liquid crystal (CLC), which simplifies the traditional optical analog computing system by taking advantage of the CLC reflecting the light with specified circular polarization and provides a new, to the best of our knowledge, idea for the integration of optical analog computing systems. Meanwhile, we present results in which a section of an insect foot is observed using the reflective optical analog computing system, which may develop valuable applications in biomedical imaging.
在过去几十年中，光类比计算在图像处理和光学工程领域引起了广泛的关注。在这里，我们提出了一种基于胆甾相液晶（CLC）的反射式光类比计算系统，该系统利用 CLC 反射特定圆偏振光的特性，简化了传统的光类比计算系统，为光类比计算系统的集成提供了一个新的思路。同时，我们还展示了使用反射式光类比计算系统观察昆虫足部的一部分的结果，这可能为生物医学成像开发有价值的应用。
