Paper Abstract

We designed a new type of array illuminator based on the Talbot effect to optimize the optical throughput of large-aperture phase-only spatial light modulators. The illuminator consists of a three-level phase relief and produces an intensity distribution with a duty cycle of 80%. To investigate both near and far field, we formulated an algorithm using the Fresnel-Kirchhoff diffraction formula and computed intensity and phase patterns. A tolerance analysis on typical fabrication errors and their effects on the optical throughput is presented.
