Title:
距離測定装置、及び立体形状測定装置。
Document Type and Number:
Japanese Patent JP6730483
Kind Code:
B2
Abstract:
An object is to provide a technology capable of realizing miniaturizing of a measurement unit in a distance measuring device. The distance measuring device including a light emitting unit that outputs measurement light, a polarization state control unit that controls polarization of the measurement light output from the light emitting unit, and an optical path switching element that selectively emits the measurement light controlled by the polarization state control unit, in which the polarization state control unit controls the polarization so as to emit the measurement light in a plurality of directions from the optical path switching element, and the optical path switching element receives reflected light with respect to an object of the measurement light emitted from the optical path switching element, the reflected light being used to measure a distance to the object.
