光学新事物滤波器及其应用
Optical Novelty Filter and Its Applications
摘要
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。
Abstract
Optical novelty filter is a photonic device which shows new phenomena in an input image compared with the input recent history.Optical novelty filter is extensively applied in detecting and tracing the moving object, and measuring the change of the phase. The materials used for optical novelty filter are classified as inorganic crystal, such as barium titanate crystal and doped barium titanate crystal, and organic polymers, such as various photorefractive polymers and bacterior-hodopsin. The principle of optical novelty filter and its applications in different fields were introduced.
