Volume Digital Holographic Wavefront Sensor Phase 2

Through the execution of our Phase 1 effort, Nutronics, Inc. and Montana State University developed an improved means to optimize the Pellizzarri cost functional for coherent imaging using digital holography. Our algorithm developed during the Phase 1 effort accelerates convergence times by a factor of 20-40 for the majority of scenarios evaluated. Our proposed Phase 2 effort has a two-fold focus: (1) video rate (objective of kHz rate) implementation of our algorithm using a single-layer phase solution; and (2) continuing algorithm development for a multi-layer Volume Digital Holographic Wavefront Sensor (VDHWFS). VDHWFS based imaging offers the potential to provide the equivalent of wide field of view adaptive optics (AO) compensated imaging, but without the added complexity of AO components and hardware.
