Super resolution using random patterns and blind deconvolution
Broadband structured illumination patterns are used to produce super-resolution images using a DMD in conjunction with an incoherent light source. By projecting patterns of varied spatial frequencies and using blind deconvolution of an unknown point spread function, super-resolution is achieved. We explore the impact of resolution loss via the transmit and receive leg of the microscope and compare against the reconstruction techniques. Using a randomly distributed pattern provides a low cost solution to obtaining information similar to that produced in confocal microscopy and other methods of structured illumination, without the requirement of precise projection patterns, coherent light sources, or fluorescence.
