Abstract:
Systems and methods can align of one or more optical beams with respect to one another, an optical axis, a far-field location, and/or a near-field location. An example method includes coupling, with an index-matched epoxy, a plurality of adjustable optical surfaces and an optical element. Each adjustable optical surface of the plurality of adjustable optical surfaces is associated with a respective light-emitter device of a plurality of light-emitter devices. Additionally, the method includes causing at least one light-emitter device to emit light that interacts with at least one adjustable optical surface and an optical element to provide a transmitted light beam. The method also includes receiving information about a beam profile of the transmitted light beam, comparing the beam profile to a desired beam profile, and adjusting a position of the at least one adjustable optical surface with respect to the optical element based on the comparison.
