We describe a new concept of an electro-optical sensor with the capability of simultaneous spatial and spectral filtering. It is based on a spatial light modulator, and in combination with the technique of wavelength multiplexing, it enables one to manipulate the spectral content of an indicated spot within the field of view of the sensor. This new concept allows the attenuation of monochromatic light of undetermined wavelengths in particular and is of worth for imaging vision systems to suppress unwanted detector overexposure.
我们描述了一种具有同时进行空间和光谱滤波能力的电光传感器的新概念。它基于空间光调制器，并与波长复用技术相结合，使人们能够在传感器视场内操纵指定光斑的光谱内容。这一新概念尤其允许衰减未确定波长的单色光，对于成像视觉系统抑制不必要的探测器过度曝光具有重要价值。
