Active illumination scanning imager
First Claim
1. Active-illumination scanning imager, comprising a light source for producing a light beam, an optical collimator for collimating said light beam in at least one direction transversal to a beam direction, a scanning mirror for scanning said light beam through a scene to be imaged and a light detector arranged with respect to said scanning mirror in such a way as to receive a fraction of said light beam reflected from said scene, via said scanning mirror;
- wherein said imager further comprises an actuator configured to position at least one of said light source and/or said optical collimator relative to one another and/or to position said light detector relative to said scanning mirror, and a controller operatively connected to said actuator for controlling said positioning.

Abstract
An active-illumination scanning imager (10) comprises a light source (14) for producing a light beam (16), an optical collimator (18) for collimating the light beam, a scanning mirror (20) for scanning the light beam through a scene (12) to be imaged, and a light detector (22) arranged with respect to the scanning mirror in such a way as to receive a fraction (24) of said light beam reflected from said scene, via the scanning mirror. The imager further includes an actuator (40) configured to position the light source and/or the optical collimator relative to each other and/or the light detector relative to the scanning mirror, and a controller (46) operatively connected to the actuator for controlling the positioning.
