Abstract: A system includes multiple laser diode modules that are spatially separated and configured to generate multiple optical beams that propagate at angles relative to each other. The system also includes an optical element having at least one entrance surface and at least one exit surface. The optical element is configured to receive the optical beams at the at least one entrance surface and output each optical beam through the at least one exit surface such that the output optical beams are closely spaced, substantially the same size, and substantially parallel to each other at a common distance downstream from the optical element, and the optical beams all share a common downstream image plane.

Abstract: System and method for sensor alignment. In one example, a reimaging optical system includes reimaging foreoptics positioned to receive and reimage incident electromagnetic radiation to produce an intermediate image plane and output an optical beam of the received incident electromagnetic radiation, an imaging optical apparatus positioned to receive the optical beam and focus the electromagnetic radiation of the optical beam onto a first focal plane, a first imaging sensor positioned at the first focal plane and configured to produce a first image responsive to receiving the electromagnetic radiation of the optical beam, an alignment object selectively positioned at the intermediate image plane and configured to superimpose an alignment tool upon the first image, and a controller coupled to the first imaging sensor and configured to perform an alignment process for the first imaging sensor based on at least a position of the alignment tool in the first image.

Abstract: An apparatus includes an in-line reflective optical system configured to receive an input optical beam and provide an output optical beam. The in-line reflective optical system includes first and second powered mirrors aligned back-to-back. The first powered mirror is configured to reflect the input optical beam as a first intermediate beam. The in-line reflective optical system also includes first and second reflective surfaces respectively configured to reflect the first intermediate beam as a second intermediate beam and to reflect the second intermediate beam as a third intermediate beam. The second powered mirror is configured to reflect the third intermediate beam as the output optical beam. A spacing between the first and second reflective surfaces and the first and second powered mirrors is adjustable to control a focus of the output optical beam without introducing boresight error in the output optical beam.
