Abstract: A distance measuring apparatus includes a light source that emits a light beam, a scanning device that performs beam scanning where an emission direction of the light beam is changed, a photodetector that receives light reflected from measurement points on a target irradiated with the light beam and that outputs detection signals, a processing circuit that calculates distances to the measurement points on a basis of the detection signals, and a control circuit that controls the scanning device. The control circuit determines a step angle of the beam scanning in such a way as to reduce differences in density of the measurement points between areas of the target.

Abstract: A measurement system includes a light source, an optical detector, and a processing circuit. The light source emits irradiation light to be applied to multiple measurement points included in at least one evaluation region of a surface of an object. The optical detector receives reflected light returned from the multiple measurement points and outputs a detection signal. The processing circuit calculates and outputs a roughness parameter regarding an uneven shape of the at least one evaluation region, based on the detection signal. The processing circuit corrects the roughness parameter in accordance with an angle of incidence of the irradiation light incident on the at least one evaluation region, a measurement distance in the at least one evaluation region, or intensity of received light obtained as a result of the at least one evaluation region being irradiated with the irradiation light.

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.

Abstract: An optical filter array is used in a photodetection device that generates image data separately for each of N (where N is an integer greater than or equal to 4) wavelength bands. The optical filter array includes a plurality of optical filters. The plurality of optical filters include plural types of optical filters differing in transmittance from each other in each of the N wavelength bands. Assuming that pi is an average of transmittances of the plurality of optical filters for light in an ith wavelength band (where i is an integer greater than or equal to 1 and less than or equal to N) of the N wavelength bands, a standard deviation of the average μi of the transmittances for the N wavelength bands is less than or equal to 0.13.

Abstract: A light detecting device includes: a filter array including filters two-dimensionally arrayed and an image sensor including light detection elements. Each of first and second filters included in the filters includes a first reflective layer, a second reflective layer, and an intermediate layer therebetween and has a resonance structure having resonant modes whose orders are different from each other. A refractive index and/or a thickness of the intermediate layer in the first and second filters is different depending on the filter. A transmission spectrum of each of the first and second filters has local maximum value of transmittance at each of wavelengths included in a wavelength region, and the wavelengths correspond to the resonant modes, respectively. The image sensor is disposed at a position where the image senor receives passing light that passes through the filter array, to detect components in the wavelengths included in the passing light.
