Image-based wave front sensorless adaptive optics
Booth MJ., Débarre D., Wilson T.
We present an overview of a wave front sensor-less adaptive optics scheme based upon the optimisation of the low spatial frequency content of images. Aberrations are expanded as a series of Lukosz functions as this permits the independent optimisation of each aberration mode. The scheme is demonstrated in an incoherent transmission microscope. It is shown how the method is related to so-called 'image sharpening' techniques.
