Problems solved by technology

When the spatial light modulator works in the scene where multiple wavelengths switch rapidly over time, this method has the disadvantage that the correction response speed cannot keep up, or when the spatial light modulator is in the working mode without a host computer, it cannot be adjusted conveniently.

Abstract

The invention discloses a Gamma parameter setting method for a spatial light modulator, and relates to the field of development and application of spatial light modulators. The system comprises a Gamma memory, an instruction set and an interaction device designed according to the instruction set, the interaction device comprises a scale knob, a trigger level interface and other different implementation methods. Specifically, according to the method, multiple groups of Gamma parameters and LUT table data are pre-stored in a spatial light modulator hardware memory, then a specific Gamma value isset in real time or asynchronously through an instruction set, and the interaction mode comprises a series of modes such as a trigger level interface, a scale knob and an automatic timing sequence. According to the technical scheme, the spatial light modulator can automatically select different Gamma values in real time, or manually and directly select the Gamma values through hardware operation,so that the control precision and usability of the spatial light modulator are improved.

Description

technical field [0001] The invention relates to the development and application field of a spatial light modulator, in particular to a method for users to quickly realize the Gamma correction function of a spatial light modulator. Background technique [0002] The spatial light modulator is a wavelength- and temperature-sensitive optical device, and its electro-optic characteristics vary greatly at different wavelengths. Users expect the spatial light modulator to have the ability to work with a wide range of optical wavelengths. If it is a liquid crystal spatial light modulator, the characteristics of the liquid crystal material will change with temperature. Therefore, it is necessary to set the operating parameters of the spatial light modulator according to the wavelength or temperature conditions when using it, so as to obtain the expected EO curve, that is, the gray amplitude Curve or grayscale phase curve, which is convenient for users to improve the precision and accu...
