光学新事物滤波器是一种光子学器件,只显示与输入图像相比新出现的或者是有变化的部分,而静止的图像部分在输出图像中不被显示。光学新事物滤波器被广泛用于探测和跟踪移动的物体,相位测量以及生物医学等方面。新事物滤波器所用的材料目前有两大类:一类是无机晶体,主要是钛酸钡晶体以及掺杂的钛酸钡晶体;另外一类是有机光学材料,包括各种光折变聚合物和生物光子学材料细菌视紫红质等。介绍了各种新事物滤波器的工作原理以及在各个领域的应用。
An optical novelty filter is a photonic device that shows only newly emerging or changing portions of an input image while still image portions are not displayed in the output image. Optical novelty filters are widely used to detect and track moving objects, phase measurements, and biomedical aspects. There are two main types of materials used in new things filters: one is inorganic crystals, mainly barium titanate crystals and doped barium titanate crystals; the other is organic optical materials including various photorefractive polymers And biophotonics materials such as bacteriorhodopsin. Introduced a variety of new things filter works and in various fields of application.
