Scanning Projectors And Image Capture Modules For 3D Mapping
First Claim
1. Apparatus for mapping, comprising:
- a radiation source, which is configured to emit a beam of radiation;
a first scanning mirror, which is configured to receive and scan the emitted beam in a first direction over a selected angular range within a region of interest;
a detector and optics, which define a sensing area of the detector;
a second scanning mirror, which is configured to scan the sensing area over the selected angular range in the first direction in synchronization with the scanned beam from the radiation source;
a scanner, which is configured to scan both the emitted beam and the sensing area over the region of interest in a second direction, which is perpendicular to the first direction; and
a processor, which is configured to process signals output by the detector in order to construct a three-dimensional (3D) map of an object in the region of interest.

Abstract
Apparatus for mapping includes a radiation source, which is configured to emit a beam of radiation. A first scanning mirror is configured to receive and scan the emitted beam in a first direction over a selected angular range within a region of interest. A detector and optics define a sensing area of the detector. A second scanning mirror is configured to scan the sensing area over the selected angular range in the first direction in synchronization with the scanned beam from the radiation source. A scanner is configured to scan both the emitted beam and the sensing area over the region of interest in a second direction, which is perpendicular to the first direction. A processor is configured to process signals output by the detector in order to construct a three-dimensional (3D) map of an object in the region of interest.
