<p>A spectral band variable type radiometer of the present invention has a prism (32) for dispersing an incident light to provide a plurality of spectrums, and two-dimensional photoelectric elements array (33) for detecting the spectrums, respectively, and a plurality of switches (34) connected to the photoelectric elements. The switches are controlled so that the radiometer can observes spectrums in a desired spectral band and width. <IMAGE></p> |
