SINGLE-PASS IMAGING SYSTEM USING SPATIAL LIGHT MODULATOR AND ANAMORPHIC PROJECTION OPTICS

摘要

PROBLEM TO BE SOLVED: To provide an imaging system that achieving a single-pass, high resolution, and high speed without any high-intensity light source passing through a spatial light modulator.

SOLUTION: The imaging system includes: a homogenous light generator 110 for generating homogenous light from high energy IR lasers; a spatial light modulator 120 including light modulating elements arranged in a two-dimensional array; and an anamorphic optical system 130. The light modulating elements are disposed such that each modulating element receives an associated homogenous light portion, and is individually adjustable between an ON-modulated state and an OFF-modulated state, whereby in the ON-modulated state each modulating element modulates its received homogenous light portion such that the associated modulated light portion is directed onto a corresponding region of the anamorphic optical system 130.
