Abstract
It is shown that a 2-D binary phase grating with a phase step of π/2 produces an amplitude checker image at planes distant ΖT/8, and hence is suitable for array generation. This study is in sharp contrast to that reported earlier where a phase step of π is used, and a cross grating is generated.
