Abstract:
According to an embodiment, an image capture apparatus comprises a light emitter, a beam scanner aligned to receive emitted light and operable to scan the light in a two-dimensional pattern, imaging optics aligned to receive the scanned two-dimensional pattern and image the pattern onto an object, and to collect light scattered from the object, a detector to receive scattered light from the imaging optics, an electronic controller c operable to receive an electrical signal from the detector corresponding to the received scattered light, and an actuator operable to modify the relative alignment between the beam scanner and the imaging optics to change an imaged location on the object. According to an embodiment, a method for capturing an image comprises scanning a beam of light through imaging optics onto a location on a surface, detecting light scattered by the surface, and steering the beam scanner relative to the imaging optics to change the trajectory of the scanned pattern. According to an embodiment, a system for scanning a field of view comprises a light source, an optical fiber, a MEMs scanner aligned to receive the light from the optical fiber and operable to scan the light through a partially-reflective imaging optic in a pattern, and a photo-detector aligned to receive light scattered from the field of view.
