Random structured illumination patterns are used to demonstrate effective sectioning as well as super-resolution images 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. Random patterns produce more consistent sectioning and super-resolution given an unknown optical transfer function. Further, 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.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
