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.
