グする構成になることを特徴とする光検出器。[Claims for Utility Model Registration] (1) In a photodetector that detects optical power by stepping an optical path using a tuning fork oscillator, when the incident light is continuous light, the tuning fork oscillator steps the optical path. The photodetector is characterized in that the tuning fork vibrator is configured to avoid the optical path when the incident light is modulated light. (2) A photodetector that detects optical power by stepping on an optical path, characterized in that the photodetector has a configuration in which the optical path is stepped in response to incidence of continuous light.
