Abstract
Aiming at defect of a large amount of redundant data of the traditional laser imaging technology
a new kind of laser illuminated imaging method based on compressed sensing( CS) is proposed. The basic principle of CS is elaborated. Simulation of image restoration algorithm is carried out. Simulation result demonstrates that with the increase of sampling rate
the quality of imaging increases obviously; with the increase of sparsity of the target object
number of required samplings for image reconstruction decrease. Imaging experimental system is designed
image recovery of 32 pixel × 32 pixel is realized. Feasibility of this imageing technology is confirmed.
