Abstract: An interferometer system comprising an optical detector including a substrate and a two-dimensional array of pixels disposed on the substrate is provided. The interferometer system may further comprise an interferometer disposed proximate the optical detector without an optical element between the interferometer and the optical detector. The interferometer may include a first plate positioned proximate the substrate and extending over the two-dimensional array of pixels, a second plate spaced apart from the first plate, the first and second plates defining an optical gap between them, and at least one actuatable spacer positioned between the first plate and the second plate and configured to space apart the first and second plates from one another and to selectively alter a thickness of the optical gap.

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.
