Electrooptical modulation characteristics of charge-addressed ferroelectric crystal spatial light modulators

A charge sensitivity modulation transfer function (MTF) of charge-addressed ferroelectric crystal spatial light modulator, which consists of oblique-cut crystal plate and two isotropically dielectric layers, is derived as a function of the geometrical parameters, dielectric and electro-optic coefficients. The electrooptical modulation characteristics such as sensitivity, resolution and longitudinal- to transverse-transfer ratio are extracted from this function. The orientation dependence of these characteristics for (ZYw)θ-cut LiNbO₃ are presented with regard to the MSLM configuration. The results indicate some improvement aspects for device design
