20100290120 | SLIT APERTURE FOR DIFFRACTION RANGE FINDING SYSTEM - A method and system for forming a focused image on an image plane of a diffraction range finder with a variable pitch diffraction grating. Diffracted light is propagated through a lens and slit assembly and onto an image plane of a camera, the diffracted light having been diffracted by the variable pitch diffraction grating. The lens and slit assembly includes lens elements and a slit. The slit is surrounded by opaque material that is opaque to the diffracted light passing through the slit. The slit has a shape characterized by a long dimension and a short dimension that is shorter than the long dimension. | 11-18-2010 |
20100110445 | SLIT APERTURE FOR DIFFRACTION RANGE FINDING SYSTEM AND METHOD FOR USING THE SLIT APERTURE TO FORM A FOCUSED IMAGE - A method and system for forming a focused image on an image plane of a diffraction range finder with a variable pitch diffraction grating. The system includes the variable pitch diffraction grating and a slit through which diffracted light may traverse after having been diffracted by the diffraction grating, wherein the diffracted light is configured to form a focused image on an image plane of a camera after traversing the slit. The method propagates the diffracted through the slit and onto the image plane of the camera, wherein the diffracted light had been diffracted by the variable pitch diffraction grating. | 05-06-2010 |
