Abstract
A spectroscopic measurement apparatus includes an actuator that is driven by applying a drive voltage, a gap detector that detects a dimension of a gap, and a voltage control section including a feedback loop that controls the drive voltage depending on a detection result of the gap detector. The voltage control section includes a comparator that outputs a voltage signal at a High level VH if an absolute value of a deviation between a drive amount of the actuator and a setting value of the drive amount exceeds a predetermined threshold based on the detection result after a predetermined time elapses from the start of driving of the actuator.
