Title:
OPTICAL FIBER CABLE, CONTROLLER CONNECTED THERETO, AND OPTICAL INTERFERENCE RANGING SENSOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2024/070358
Kind Code:
A1
Abstract:
The present invention makes it possible to easily adjust the length of an optical fiber cable in accordance with the measurement environment. An optical fiber cable according to one embodiment of the present invention is used in an optical interference ranging sensor having a light source unit for supplying light while sweeping the wavelength at a fixed periodicity, a light splitting means for splitting the light into measurement light and reference light, an optical multiplexing means for multiplexing the reference light and reflected light from a measurement target, an interference light detection means for detecting interference light multiplexed by the optical multiplexing means, and a distance calculation means for calculating the distance to the measurement target by subjecting the interference light to a frequency analysis, the optical fiber cable having: a first optical fiber for guiding at least a portion of the light supplied from the light source unit and the measurement light that has been split off by the splitting means; and a second optical fiber for guiding at least a portion of the light supplied from the light source unit and the reference light that has been split by the splitting means.
