An optical multichamel detector system detects whole spectra simultaneously.Therefore it enables spectral measurement of light fluctuating rapidly in intensity or in spectral composition, which is difficult or impossible by other means.An optical multichamel detector system including original computer programs has been constructed and spectra of ultraviolet light from arc weldings have been measured by this system.Complicated spectra containing a great number of spectral lines have been obtained, which could not be measured before the development of optical multichamel detector systems.
