Paper Abstract

The experimental demonstration of a blind deconvolution method on an imaging system with a Light Sword optical element (LSOE) used instead of a lens. Try-and-error deconvolution of known Point Spread Functions (PSF) from an input image captured on a single CCD camera is done. By establishing the optimal PSF providing the optimal contrast of optotypes seen in a frame, one can know the defocus parameter and hence the object distance. Therefore with a single exposure on a standard CCD camera we gain information on the depth of a 3-D scene. Exemplary results for a simple scene containing three optotypes at three distances from the imaging element are presented.
