A Digital Zoom Lens Method Basedon LCOS

LIU Chunmei;GAO Xiangmei;College of Economy and Technology,Anhui Agricultural University;  
This paper presents a method of the digital zoom lens based on Liquid Crystal on Silicon( LCOS). The phase diagram of digital lens controls LCOS to modulate the incident lightwaves,achieving the functions of digital lens of LCOS. By switching on the phase modulation diagram with different focal lengths on LCOS,the functions of the digital zoom lens based on LCOS can be realized. By setting up the optical zoom system based on LCOS,and combining the experimental results and theoretical analysis,the feasibility of the method is verified.
