ABSTRACT:
In order to improve spectral measurement accuracy during high-speed wavelength shifting, the appropriate sensitivity of the detection system is maintained by, prior to measurement of a sample, measuring the voltage value, then storing this value into a table, and maintaining the voltage value to be applied to the photodetector, and during measurement of the sample, reading out the maintained voltage value and applying it to the photodetector.
