Abstract
A laser projector steers an outgoing beam of light onto an object, passing light returned from the object through a focusing lens onto an aperture rigidly coupled to an optical detector.
Claims20
An apparatus comprising:
- a light source operable to emit a beam of outgoing light;
- a beam-steering system operable to steer the beam of outgoing light onto an object;
- a first focusing lens operable to receive light returned from the object;
- an aperture operable to receive light from the first focusing lens;
- an optical detector rigidly coupled to the aperture;
- and
- an adjustment stage configured to adjust the aperture in x-, y-, and x-directions, wherein adjustment in the z-direction changes a distance between the aperture and the optical detector.

A method comprising:
- providing a light source, a beam-steering system, a first focusing lens, an aperture, an optical detector rigidly coupled to the aperture, and an adjustment stage;
- emitting a beam of outgoing light with the light source;
- steering the beam of outgoing light onto an object with the beam-steering system;
- receiving through the first focusing lens light returned from the object;
- and
- adjusting the adjustment stage in an x-, y-, and z-direction to pass the returned light onto the aperture, wherein the z-direction adjustment changes a distance between the aperture and the optical detector.
