Fast & Furious focal-plane wavefront sensing.
We present two complementary algorithms suitable for using focal-plane measurements to control a wavefront corrector with an extremely high-spatial resolution. The algorithms use linear approximations to iteratively minimize the aberrations seen by the focal-plane camera. The first algorithm, Fast & Furious (FF), uses a weak-aberration assumption and pupil symmetries to achieve fast wavefront r...
متن کاملPrecision Photonic Readout for Focal Plane Signals
We will present the development of a remote Precision Photonic Readout for Focal Plane Array Detectors. Its underlying principles, design and tests as well as limitations will be discussed. The design, in essence, constitutes a remote, via fiber optics, analog-to-digital converter, where the low level focal plane signals are encoded as differential optical phase shifts. These phase shifts are t...
متن کاملFOCAL POINT AND FOCAL K-PLANE
This paper deals with the basic notions of k-tautimmersions . These notions come from two special cases; that is, tight and taut immersions. Tight and taut based on high and distance functions respectively and their basic notions are normal bundle, endpoint map, focal point, critical normal. We generalize hight and distance functions to cylindrical function and define basic notions of k-taut ...
متن کاملAdaptive Wavefront-Correction Algorithms Using Focal-Plane Array Intensity Measurements
Earth’s atmospheric turbulence induces aberrations in the wavefront of the optical signal from a distant spacecraft. These aberrations cause diffusion and spreading of the signal energy in the receiver’s focal plane, potentially resulting in an increase in bit-error rate (BER) by several orders of magnitude when significant background radiation is present, such as during daytime operation. The ...
متن کاملA Focal Plane Visual Motion Measurement Sensor
A motion detection algorithm, based on biological and computational models, for focal plane implementation has been developed. This Temporal Domain Optical Flow Measurement (TDOFM) algorithm uses computational components which have direct and compact electronic counterparts. It uses a binary image of zero-crossings, 2 level analog signals, the signs of spatiotemporal derivatives, 1-b multiplica...
