Abstract: A measuring device includes: a light source; an interference optical system that separates light into reference light and irradiation light, generates interference light by causing interference between the reference light and reflected light generated by reflection of the irradiation light on an object; a photodetector that receives the interference light and outputs a signal corresponding to an intensity of the interference light; and a processing circuit that controls the light source and generates and outputs data on a distance and/or velocity of the object based on the signal outputted from the photodetector, in which the processing circuit causes the light source to emit light having a frequency that changes with time within a first frequency range in a first mode, and causes the light source to emit light having a frequency that changes with time within a second frequency range different from the first frequency range in the second mode.

Abstract: A measurement apparatus includes a light source, an interference optical system, a photodetector, a processing circuit, and a storage apparatus. The interference optical system splits light emitted from the light source into reference light and output light and generates interfering light between reflected light resulting from reflection of the output light on an object and the reference light. The photodetector outputs a detection signal corresponding to strength of the interfering light. The processing circuit modulates the frequency of the light outputted from the light source with a period including an up-chirp duration in which the frequency increases and a down-chirp duration in which the frequency decreases. The storage apparatus stores first correction data for the up-chirp duration and second correction data for the down-chirp duration. The processing circuit determines distance or velocity based on a signal obtained by correcting the detection signal based on the first or second correction data.
