Infrared imaging mthod using time division reticle
시간분할 회전격자를 이용한 적외선 영상구성방법
Abstract
A novel imaging method in which time-division spinning reticle samples different pixel location of input image in different time is presented. The lens collects the beam passing throughthe reticle to a photodetector. Image reconstruction is accomplished by sampling the detector output corresponding to the spinning speed of reticle. Since the time-division reticle system removed the necessity of bandpass filter bank which has sharp cut-off characteristic, high resolution image is obtained without increasing the number of filter. To confirm the validity of this method, a computer simulation and an optical experiment using visual light are presented.
