Assignee: HAMAMATSU PHOTONICS K.K.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 4:
5. The optical module according to claim 2,
wherein a zero optical path difference position of the movable mirror, at which an optical path length on the movable mirror side with which the interference light of the measurement light is caused to occur becomes the same as an optical path length on the at least one fixed mirror side with which the interference light of the measurement light is caused to occur, deviates from a central position of the resonance operation of the movable mirror, and
the processer,
performs a process of acquiring the addition value of the plurality of first measurement light intensities mutually corresponding for the same number of times, and acquiring the addition value of the plurality of first laser light intensities mutually corresponding for the same number of times as the first intensity acquisition process in a first half or a second half in each of the odd-numbered cycles, and
performs a process of acquiring the addition value of the plurality of second measurement light intensities mutually corresponding for the same number of times, and acquiring the addition value of the plurality of second laser light intensities mutually corresponding for the same number of times as the second intensity acquisition process in a first half or a second half in each of the even-numbered cycles.
