The idea is to use an array of microlenses in order to capture light coming from many different angles. By storing this data, it is possible to bring different focal planes into focus in post-processing offline. It has been <a href=\"http:\/\/graphics.stanford.edu\/projects\/lfmicroscope\/\">implemented for wide-field microscopy<\/a>. <\/p>\n<p>The <a href=\"http:\/\/graphics.stanford.edu\/\">Stanford Computer Graphics Laboratory<\/a> has released some Mac OSX <a href=\"http:\/\/graphics.stanford.edu\/software\/LFDisplay\/\">software<\/a> for trying this yourself.
