The nonlinear amplitude transmittance or amplitude reflectance-to-writing light level dependence of a spatial light modulator (SLM) introduces distortions in the output response. The resulting harmonic and intermodulation distortion levels are computed for a representative SLM at several write light illumination levels. The presence of these distortions in the diffraction pattern of an image is also illustrated experimentally. The need for the technical community to quantify these distortions in a universal manner is stressed.
空间光调制器（SLM）的非线性幅度透过率或幅度反射率与写入光水平的相关性会在输出响应中引入失真。针对一个代表性的SLM，在几个写入光照明水平下计算了由此产生的谐波和互调失真水平。还通过实验说明了图像衍射图案中这些失真的存在。强调了技术界以通用方式量化这些失真的必要性。
