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.

摘要： An optical switch for switching first and second input beams linearly polarized in the same direction which has a first half wave plate for rotating the polarization optically coupled to the second input beam, the first input beam and the output of the half wave plate input to a first polarization beam displacer which provides a combined beam, the output of which is connected to a controllable half wave gate which in a passive state passes the combined beam gate and in the active state passes the combined beamed rotated by 90 degree to an output Gate in dependence of a controlled signal input to the controllable wave gate. The output of the controllable wave gate is input to a second polarization beam displacer which refracts light into first and second refracted output beams displaced from each other a predetermined distance and a second half wave plate.
