【Abstract】 Azo liquid crystal polymer (LCP) is a novel optical storage medium.In this paper,we introduced two photon induced birefringence effect in azo LCP.Based on the method of polarization angle variation,a multi scaled storage technology was proposed.The experiment result of multi scaled storage was demonstrated,and an optical system scheme for the multi scaled memory was suggested.更多还原
