THE tendency of the technique of spectral measurement is now towards sensitivity, precision,quickness, time and spatial resolving spectrum. For the spectrophotometers, which acquirespectral data with the serious method, the measurement of spectral intensity for differentwavelengths is not simultaneous. It is difficult to quickly get a spectrum, because time must bespent on tuning the dispersive device, and it is also impossible to process time and spatial Te-solving spectrum. The problems mentioned above are the fatal disadvantages for further devel-oping the spectrophotometer equipped with monochromator. The best way to solve these prob-
