Comparison of Phase Diversity and Curvature Wavefront Sensing
We compare phase diversity and curvature wavefront sensing. Besides having completely different reconstruction algorithms, the two methods measure data in different domains: phase diversity very near to the focal plane, and curvature wavefront sensing far from the focal plane in quasi-pupil planes, which enable real-time computation of the wavefront using analog techniques. By using information...
متن کاملFast Phase Diversity Wavefront Sensing for Mirror Control
We show with simulation experiments that closed-loop phase-diversity can be used without numerical guard-bands for wavefront sensing of low-order wavefronts from extended objects using broad-band filters. This may allow realtime correction at high bandwidth for certain applications. We also present a proper maximum likelihood treatment of Shack–Hartman data, which includes an imaging model to e...
متن کاملSensing wave-front amplitude and phase with phase diversity.
We show in benchtop experiments that wave-front phase estimation by phase diversity can be significantly improved by simultaneous amplitude estimation. Processing speed, which will be important for real-time wave-front control applications, can be enhanced by use of small-format detectors with pixels that do not fully sample the diffraction limit. Using an object-independent phase-diversity alg...
متن کاملOptical wavefront measurement using phase retrieval with transverse translation diversity.
We demonstrate the use of transverse translation-diverse phase retrieval as a method for the measurement of wavefronts in situations where the detected intensity patterns would be otherwise undersampled. This technique involves using a smaller moving subaperture to produce a number of adequately sampled intensity patterns. The wavefront is then retrieved using an optimization jointly constraine...
متن کاملGeneralized phase diversity for wave-front sensing.
Phase diversity is a phase-retrieval algorithm that uses a pair of intensity images taken symmetrically about the wave front to be determined. If these images are taken about the system input pupil this is equivalent to a curvature-sensing algorithm. Traditionally a defocus aberration kernel is used to produce the phase-diverse data. We present a generalization of this method to allow the use o...
