Title:
RANGEFINDER AND RANGEFINDING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/122637
Kind Code:
A1
Abstract:
One configuration of a rangefinder according to the present disclosure is provided with an optical device (116), a light receiving unit (120), and a calculating unit (134). The optical device (116) outputs an output light. The output light is configured such that the oscillation frequency of the light emission amount periodically changes in response to a signal that has a periodically changing frequency. The light receiving unit (120) detects reflected light, which is the output light of the optical device (116) reflecting from a target object (10). The calculating unit (134) calculates the distance to the object (10) on the basis of the difference in frequency between the output light and the reflected light.
