測定装置。 It uses a light emitting element that blinks at a constant frequency to project infrared light toward an object, and a position detection element PSD that receives the infrared light reflected from the object and outputs a signal according to the receiving position. In the distance measuring device, there are two amplifiers that amplify both output signals of the position detection element, two filters that pass the signal in the blinking frequency band of the light emitter included in the output signal of each amplifier, and a signal that passes through each filter. It is equipped with two detectors that detect each signal, extract only the signal corresponding to the infrared light component from the light emitter, and use it for distance measurement calculation. A distance measuring device characterized by controlling the amplification degree of.
