Abstract

Object image grating self-tiling reduces difficulties of obtaining an ideal grating tiling condition by eliminating three tiling errors in six within a tiled grating. However, this may bring two potential problems: higher requirements of adjustment accuracy and maintaining stability. To examine the application values of this grating tiling configuration, the performance of object image grating self-tiling and traditional grating tiling configurations on accuracy and stability are compared theoretically and experimentally. Adjustment accuracy requirements of two grating tiling configurations are calculated, a comparative experiment of long-term stabilities is demonstrated, and relevant theoretical simulation analyses are developed to explain the experiment results.
