Title:
OPTICAL SCANNER
Document Type and Number:
WIPO Patent Application WO/2022/070950
Kind Code:
A1
Abstract:
In the present invention, an optical phased array (3) is configured so that the phases of a plurality of branched light beams obtained by branching light supplied from a light source (2) are individually controlled using a scanning phase amount, and scanning using a light beam is accomplished via radiation from an antenna array having a plurality of antenna elements. A monitoring light receiving unit (6) is configured to receive light radiated from the optical phased array. A signal processing unit (7) is configured to detect the characteristics of light beams from the detection results of the monitoring light receiving unit, and to generate a phase adjustment amount for correcting the scanning phase amount so that the characteristics detection value matches with a design value prepared in advance.
