検出回路。An optical transmission device that transmits a signal transmitted from a light emitting element and a light receiving element, comprising: a clock signal source that forms a clock pulse for driving the light emitting element; a delay amplifier that delays an output signal of the light receiving element; It is composed of a phase difference pulse generator that forms a phase difference pulse between the output of the delay amplifier and the clock pulse, and a gate circuit. A photodetection circuit that detects transmitted light depending on the presence or absence of an output from a gate circuit.
