An optical distance measuring apparatus including a light source (1), a variable mirror (2) scanning the light on an object (14), a receiving device (3) receiving light from the object (14), a detected signal amplifying unit (6) detecting a light receiving signal obtained by the receiving device (3), an amplification control unit (7) detecting a set target value of light sensitivity of the receiving device (3) or sets the light sensitivity based on a light quantity of reflected light, and a distance calculation unit (11) detecting a flight time of the ranging light from a light emitting signal and calculating a distance up to the object (14), wherein in a first scan period, the amplification control unit (7) detects the set target value based on a light quantity of the reflected light, and in a second scan period, the amplification control unit (7) sets sensitivity of the receiving device (3) to the set target value and the distance calculation unit (11) calculates the distance. |
