PURPOSE:To enable electric selection of light with a disired wavelength with a simple construction by selectively detecting a series data pertaining to light analyzed with a plurality of photoelectric conversion elements arranged one- dimensionally. CONSTITUTION:A light analyzed with a spectroscope 10 is incident into a photoelectric conversion element train body 20 comprising a plurality of charge storage type photoelectric conversion elements arranged one-dimensionally whose analog output is sent out as series data in response to rays of light different in the wavelength by a shift register pulse. Then, a wavelength signal detection circuit 40 selectively detects analog data with the desired from among the series data from the element train body 20 according to a control signal corresponding to the position of the photoelectric conversion element. Thus, the colorimetric detector thus obtained can detect a plurality of wavelengths close to each other with a simple construction. |
