"advanced algorithms enabled reconstruction of high-resolution images equivalent to those obtained with large-aperture detection... extended coherent light sources introduces speckle interference and loss of object information, but mitigated by continuously collecting multiple images of moving objects from same camera position, and then registering and averaging them... a single small-aperture camera yielded images equivalent to those obtained with 2.5X larger aperture detection... applicable to microscopic and macroscopic"
