OPRA OPRA = Otf-based Phase Retrieval Analysis OTF-based (duh); the data and model are expressed in the Fourier plane Use Levenberg-Marquardt minimisation The following quantities can be free parameters phase (modal, Zernikes/DH/KL or can use yao machinery in 3D) image pixel size/lambda defocus scale 2D gaussian kernel (vibrations) differential image positions and intensity in 3D mode Uses numerical finite difference. Slow, but arbitrary recipes/parameters can be easily introduced (testing tool for now). Speed is an issue for use w/ CANOPUS. OSA, AO Session, Toronto, July 10-14, 2011 Wednesday, 28 September 11 13
