摘要： A distance-measuring apparatus includes a light emitter to emit light with modulated frequency to an object, a light receiver to receive the light that is emitted from the light emitter and returns as reflected by the object, and a controller to measure, based on radiation intensity of received light by the light receiver, a length of time between a time at which the light is emitted by the light emitter and a time at which the light is received by the light receiver to obtain a distance to the object. The controller performs a first measurement in which the light emitter is made emit the light at a first modulation frequency for a first irradiation time and a second time, the second irradiation time being longer than the first irradiation time, to measure the length of time by the time at which the light is received by the light receiver a first plurality of times. The controller performs a second measurement in which the light emitter is made emit the light at a second modulation frequency for a third irradiation time to measure the length of time by the time at which the light is received by the light receiver a second plurality of times fewer than the first plurality of times. The third irradiation time is longer than the first irradiation time and is shorter than the second irradiation time. Both reduction in aliasing and increase in dynamic range can be achieved.
