Patent ID: 10866311

Abstract:
A distance measuring device according to an embodiment includes a light source, an irradiation optical system, a light-receiving optical system, a sensor, an extractor, an adjuster, a signal generator, and a distance measurer. The light source intermittently emits laser light. The irradiation optical system reflects the laser light. The light-receiving optical system receives reflected light of the laser light via the mirror. The sensor includes a plurality of light receiving elements. The extractor extracts light receiving elements used for measurement of a distance to the measurement target object. The adjuster adjusts, according to an amplification factor corresponding to the light receiving elements extracted by the extractor, signal values of the electric signals of the light receiving elements. The signal generator generates time-series signals for measurement on the basis of the electric signals adjusted by the adjuster. The distance measurer measures the distance to the measurement target object.
