Abstract
We experimentally explored the reconstruction of the image of two point sources using a sequence of random aperture phase masks. The speckled intensity profiles were combined using an improved shift-and-add and multi-frame blind deconvolution to achieve a near diffraction limited image for broadband light (600-670 nm). Using a numerical model we also explored various algorithms in the presence of noise and phase aberration.
