Improvement of the fringe printer on printing speed

Abstract

We have been developing fringe printer that can output a holographic fringe image calculated as a computer-generated hologram. The printer demagnifies the fringe pattern displayed on liquid crystal display panel and projects it onto a holographic recording material. Previous fringe printer lens had problems of low diffraction efficiency and distortion of interference fringes due to aberration. In this paper, improvement of diffraction efficiency and interference fringe distortion are performed by changing to a lens with aberration correction.
