Optical state estimation using wavefront data
WebModal estimation of wave-front phase from phase derivatives is discussed. It is shown that it is desirable to minimize the number of modes estimated and the number of … WebThe Airborne Aero-Optical Laboratory has produced a large database of aero-optical measurements with a high-speed, high-resolution Shack Hartmann wavefront sensor. The data have been collected over a wide range of flight conditions. An analysis of the statistical characteristics of the subsonic and early transonic data is performed to assess the …

WebJul 1, 2013 · Abstract. A state-space disturbance model and associated prediction filter for aero-optical wavefronts are described. The model is computed by system identification from a sequence of wavefronts measured in an airborne laboratory. Estimates of the statistics and flow velocity of the wavefront data are shown and can be computed from the … WebSPIE Digital Library Proceedings
WebA method to develop optical models of individual eyes is presented. First we choose a generic eye model as the input guess, and then apply a two-stage customization procedure. Stage 1 consists of replacing, in the initial generic model, those anatomical and optical parameters with experimental data measured on the eye under analysis. WebCurrently, the benchmark method for focal plane wavefront sensing is pair-wise DM prob-ing followed by a batch process estimation.14,15 This approach constructs a linear observation of the light field using pairs of opposite DM probing commands and then formulates the wavefront sensing as a least-squares problem.
