摘要：

A programmable kinoform using an electrically controlled birefringent liquid-crystal spatial modulator (ECB-LCSLM) is discussed. The LCSLM is capable of continuous phase modulation from 0 to 2-pi. For the kinoform generation, the phase distribution is calculated by iterative methods and recorded on the LCSLM with 16 quantizing levels. We discuss the characteristics and the structure of the LCSLM for the implementation of the programmable kinoform while comparing the computed results and optical reconstructions.
