Abstract

Aming at measure the rapid target’s spatio, temporal and spectrum characteristics data synchronously, we propose a joint spatio-temporal-spectrum super-resolution method for compressive sensing optical imaging system based DMD. Based on the CACTI and CASSI technology, we focus on the key technologies such as multi-scale joint coding and time-space-frequency multi-dimensional light field joint reconstruction algorithm using DMD. Though the accuracy of photometric characteristic data is not accurate, it can meet the requirements of non-cooperative targets emergency measurement application.
