Optical distance measurement device and optical distance measurement method

Abstract

An optical distance measurement device (10) includes a light transmission unit (11) that transmits distance measurement light to a measurement object, a light reception unit (12) that receives reflected light being reflected from the measurement object by the transmitted distance measurement light, a modulation unit (13) that generates reference light acquired by performing intensity modulation on a light source according to a distance measurement range, a detection unit (14) that generates a reception signal by causing the received reflected light and the generated reference light to interfere with each other, and a distance calculation unit (15) that calculates a distance to the measurement object, based on the transmitted distance measurement light and the generated reception signal.
