Title:
MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/017765
Kind Code:
A1
Abstract:
In the present invention, a light beam generation unit generates a frequency-modulated light beam. An optical device irradiates an object with the light beam and receives light reflected by the object as signal light. A reception unit receives the signal light that has passed through the optical device and receives light reflected by the optical device as reference light. A computation unit derives the distance to the object and/or the relative speed of the object on the basis of the frequency of interference between the signal light and the reference light.
