摘要

An improved type of Dammann grating (DG) that could generate an equal-intensity spot array which has only three phases is proposed. Numerical solutions of 1 × 4 and 1 × 5 such DGs are given. A 4 × 4 two-phase DG manufactured by very-large-scale integration (VLSI) techniques is presented. A phase-shift-interferometry-based technique that measures the intensity and sub-beam phases of beam splitting gratings is proposed. The performance measurements of the manufactured 4 × 4 two-phase DG using the proposed technique is carried out.
