摘要:
Reading light (26) is phase-modulated by a phase-modulating spatial light modulator (12), the phase-modulated reading light (26) is Fourier-transformed, and an image of the Fourier-transformed reading light is focused on an output plane (24) to form an optical pattern. In this method, 0-order light in the phase-modulated reading light (26) is blurred on the output plane (24). As the 0-order light is blurred, the luminance of the 0-order light is reduced on the output plane (24). Since the 0-order light is not blocked, the shape of the optical pattern is not limited.
摘要:
An adder unit (60e) reads a desired CGH pattern from a pattern memory unit (60a) and a phase distortion correction pattern from a distortion-correction pattern memory unit (60d) and adds both patterns together to generate a phase distortion corrected pattern. A control unit (60g) controls a phase modulation module (40) in accordance with the phase distortion corrected pattern. Accordingly, phase-modulated light based on the desired phase pattern can be generated precisely, easily and quickly.
摘要:
In a spatial light modulation device using a reflection type spatial light modulator, read light is a P-polarized light that falls incident on the light reflection layer 17 at a slant. Liquid crystal in the light modulation layer 17 is oriented so as to incline, in association with the application of voltage by the driving circuit 2, within a plane that is parallel to a normal plane which includes the optical axes of both of the incident, read light and the output, modulated light.
