  • Patent number: 10765315
    Abstract: Systems and methods for high-resolution, wide-angle viewing of a retina of an eye using an ophthalmic microscope that can view a high-resolution image of a retina formed using a wide field of view optical system. A wide field of view optical system can involve a first lens having a diffractive surface on at least one surface and a second lens housing in a shared housing. A wide field of view optical system can involve one or more lens formed from an optical grade polymer and manufactured at a cost that allows the lens to be disposable.

  • Publication number: 20180098881
    Abstract: System and method of photoaltering a region of an eye using a high resolution digital image of the eye. The system includes a laser assembly for outputting a pulsed laser beam, an imaging system for capturing a real-time high resolution digital image of the eye and displaying the digital image of the eye, a user interface receiving at least one laser parameter input, and a controller coupled to the laser assembly, imaging system, and user interface. The controller directs the laser assembly to output the pulsed laser beam to the region of the eye based on the laser parameter input.

  • Publication number: 20070201027
    Abstract: According to an exemplary embodiment of the present invention, an optical measurement apparatus includes a raster-mirror, an objective element, and a detector element. The raster-mirror includes a plurality of mirror segments that are articulated relative to adjacent mirror segments and configured to receive light from a portion of a field of view and provide a reflected light portion, where the plurality of reflected light portions comprise a reflected beam. The objective element is configured to receive the reflected beam and provide an objective beam having a plurality of objective beam portions corresponding to the plurality of reflected light portions. The detector element includes a plurality of detector portions and is configured to receive the objective beam and provide a corresponding image signal, where the plurality of objective beam portions are simultaneously imaged on the plurality of different detector portions.

  • Publication number: 20070091316
    Abstract: A multi-beam heterodyne vibrometer for analyzing vibration of an object includes an optical system and a combining element. The optical system generates a plurality of object beams and a plurality of reference beams where one of the plurality of beams has a frequency that is shifted from a frequency of the other plurality of beams. The optical system focuses each of the plurality of object beams on the object and transmits the plurality of focused object beams to the object. A portion of each of the plurality of focused object beams is reflected off of a surface of the object as a modulated object beam. The optical system collects the modulated object beams. The combining element combines each of the modulated object beams with a respective one of the reference beams into a plurality of beam pairs.
