摘要：An optical detector (110) is disclosed, the optical detector (110) comprising: atleast one spatial light modulator (114) being adapted to modify at least one property ofa light beam (136) in a spatially resolved fashion, having a matrix (132) of pixels (134), eachpixel (134) being controllable to individually modify the at least one optical property of aportion of the light beam (136) passing the pixel (134); at least one optical sensor (116)adapted to detect the light beam (136) after passing the matrix (132) of pixels (134) ofthe spatial light modulator (114) and to generate at least one sensor signal; at least onemodulator device (118) adapted for periodically controlling at least two of the pixels(134) with different modulation frequencies; and at least one evaluation device (120)adapted for performing a frequency analysis in order to determine signal components ofthe sensor signal for the modulation frequencies.
