Abstract

PURPOSE: To measure the spectrum characteristics of any position of a sample such as living body's cell or the like for short time by collecting a video signal obtained by taking the sample illuminated by a monochromatic light as a picture data at every wavelength of the light.

CONSTITUTION: A light of any wavelength is selected by a spectroscope 16 from the luminous flux of a light source 15, and a monochromatic light obtained from the spectroscope 16 is irradiated to a sample on the stage of a microscope 17. The cells of the sample thus illuminated is taken by a camera 13. A video signal thus obtained is introduced into a video signal processor 3, which converts only the video signal corresponding to the picture region specified into digital amount. The digital data thus obtained is stored in a buffer memory 51. The spectroscope 16 is controlled by an arithmetic controller 52 of a central processor 5 to control the wavelength of the monochromatic light and control the application of the data to a memory 51 to store the picture data at every wavelength in the memory 51. Since the region for collecting the data to be converted into the digital amount is limited by the controller 39 controlled by the central processor 5, the data processing time can be shortened.
