摘要: A super-resolving imaging apparatus employs diffractive optical elements placed on the imaging lens. This element, and the use of a modified Scheimpflug arrangement allow the conversion of degrees of freedom in one axis of a field of view to a larger degree of freedom in another axis in order to obtain a high resolution image with a wide depth of focus and large field of view. Replicas created by the diffractive elements are mutually shifted by subpixel amounts, and are combined using a Gabor transform, which is facilitated by a spatial mask placed over the detector array. The apparatus is suitable for performing distance estimation on an object within the field of view.
