Title: OPTICAL MEASUREMENT CONTROL PROGRAM, OPTICAL MEASUREMENT SYSTEM, AND OPTICAL MEASUREMENT METHOD
Abstract:
In a photodetection device that includes: a Fabry-Perot interference filter which has a pair of mirrors opposed to each other with a gap therebetween and in which the distance between the mirrors changes according to the potential difference between the mirrors; and a photodetector that detects light transmitted through the Fabry-Perot interference filter, the optical measurement control program according to the present invention causes a computer to carry out a process for measuring light to be measured, by acquiring an electrical signal outputted from the photodetector. The computer is caused to function as: a voltage control unit that executes, before acquisition of the electrical signal is started, control so as to gradually increase the potential difference generated between the mirrors until a set potential difference corresponding to the wavelength of the light to be measured is reached; and a signal acquisition unit that acquires the electrical signal in a state where the voltage control unit has generated the set potential difference between the mirrors.
