Abstract: In an adaptive optics module, wavefront sensing and data detection are implemented in a single device. For example, an optical-to-electrical converter converts a data-encoded optical beam to an intermediate electrical signal, which contains both the data encoded in the beam and also wavefront information about the beam. The data and wavefront information are later separated, for example by frequency filtering.

Abstract: An adaptive optics imaging system has an acquisition imaging subsystem to assist in initial acquisition and alignment of the system to a target object. A wavefront sensor in the adaptive optics imaging system is aligned to a reference object in the acquisition imaging subsystem. The target object is also aligned to the reference object. In this way, alignment of the target object with the wavefront sensor is achieved.

Abstract: A deformable mirror for an adaptive optics system includes a number of electrodes for causing deformation of the mirror. An insulating layer and a layer of conductive traces over the electrodes allow the connection points for the electrodes to be moved to a perimeter region of the mirror, which facilitates connecting the mirror to a circuit board or other equipment. In one implementation, the deformable mirror is coupled to a circuit board by a strip connector (e.g., a zebra strip connector), which is maintained in a compressed state by a retaining plate.
