The real-time image differentiating is performed with the nonlinear transforming ability of LCLV only by changing its biasing voltage. The nonlinear property of LCLV is explained from its structure and the experimental results of two methods are given.

Performances and mechanism of frequency domain optical storage were studied on a highly-efficient organic photon-gated spectral hole burning material Zn-tetrabenzoporphyrin/crotonic acid/phenoxy resin (ZnTBP/CA/PhR) film. Extremely deep holes were burnt on the broat Q(0,0) band. Data writing, reading,erasing and longterm storage at 4.2 K were demonstrated. Photo-product was detected and laser induced donor-acceptor electron transfer was evidenced responsible for the hole formation.
