【 摘 要 】

A method for the effective formation of symmetric light fields with a given phase distribution by binary diffractive optical elements is proposed. The design method is based on two-level phase quantisation of multi-level diffractive optical elements that form a basic distribution of light field. Numerical simulation of the formation of predetermined light fields is performed. The possibility of forming such light fields by a spatial light modulator is experimentally demonstrated.
