  • Patent number: 10481263
    Abstract: A range finding apparatus includes a light emission unit including a light source and a light source driver, a light detection unit, and circuitry. The light source driver supplies a plurality of drive pulses having different pulse width at different time periods. The light detection unit receives the light emitted from the light emission unit and then reflected from an object. The circuitry calculates a range to the object based on a time difference between one time point when a pulse light is emitted from the light source and another time point when light reflected from the object is received by the light detection unit. One of the drive pulses set with a smaller pulse width is set with a sine wave pattern, and another one of the drive pulses set with a greater pulse width is set with a rectangular wave pattern.
