Paper Abstract

A novel imaging technique in which time-division spinning reticles encodes different pixel locations by light modulation is presented. In this technique, a reticle samples different pixel location in different time, and photodetector collects the resulting signals. Image reconstruction is accomplished by sampling the detector output corresponding to the spinning speed of reticle. Since time-division reticle system removes the necessity of band pass filter bank which has sharp cut-off characteristic, high resolution image is obtained without increasing the number of filter. We presented computer simulation for reduced model and confirmed the validity of this technique.
