The authors developed a spectroscopic measuring system to analyze time-varying optical spectra. A charge-coupled device (CCD) linear image sensor that has 2048 pixels is used as an optical detector, so that precise and quick measurements of the optical spectrum can be made in a time-spectral region. With this system the spectral lines in the region of 340-760 nm can be measured with an interval of 2 ms for 2048 pixels. Calibration of the wavelength is possible with the use of reference lamps, and the spectral lines can be identified precisely. The application of this system to the analysis of electric arc spectra and the dynamic characteristics of a semiconductor laser is discussed.
