Title:
SENSOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/199646
Kind Code:
A1
Abstract:
Some of the electromagnetic waves emitted from an emission unit (110) and reflected by a mobile reflection unit (120) are reflected or scattered by an object, e.g. a body outside of a sensor device (10). Other electromagnetic waves emitted from the emission unit (110) and reflected by the mobile reflection unit (120) are reflected or scattered by a structure (200) positioned closer to the mobile reflection unit (120) than the object. A detection unit (122) detects the deflection angle of the mobile reflection unit (120) in a first direction (X) and second direction (Y). A correction unit (150) corrects the detection results of the detection unit (122) on the basis of the results of the reception by a reception unit (130) of the electromagnetic waves reflected or scattered by the structure (200).
