DOI: 10.1364/oe.26.014375
Abstract: Conventional deconvolution methods assume that the microscopy system is spatially invariant, introducing considerable errors. We developed a method to more precisely estimate space-variant point-spread functions from sparse measurements. To this end, a space-variant version of… read more here.

DOI: 10.1364/ol.550272
Abstract: Iterative phase retrieval (IPR) algorithms are widely used in digital optics because of their efficiency and simplicity. Conventionally, these algorithms do not consider aberrations as they assume an ideal, aberration-free optical system. Here, we propose… read more here.
