Original Abstract Submitted
An optical apparatus includes a first light receiving unit including a first avalanche photodiode, a second light receiving unit including a second avalanche photodiode whose light receiving surface is shielded from light, and a voltage control unit configured to apply a first reverse bias voltage to the first avalanche photodiode and a second reverse bias voltage to the second avalanche photodiode. The voltage control unit controls the first reverse bias voltage based on the second reverse bias voltage.
