Paper Abstract

Superresolving configurations that integrate two digital mirror devices (DMDs) in the aperture and/or in the intermediate image plane are presented. The usage of DMDs allows obtaining geometric resolution improvement, enhancing field of view (FOV), and reducing aberrations such as defocusing and blurring (obtained due to relative movement during the integration time of the camera). The idea behind all the above-mentioned applications is to use the DMDs to properly encode the space and the spatial frequency domains such that the object’s information can be separated from the above mentioned aberrations, distortions, limitations, and noises. The compressed sensing concept is applied in order to allow capturing in time-less images than the obtainable improvement factor (of resolution, of FOV, or of aberration correction).
