    Abstract: A laser beam delivery apparatus for a microscope comprises first and second optical diffusers that are configured to move in a periodic manner with a respective different frequency. Each optical diffuser may comprise a spinning disk. The laser light is spatially randomized by the first spinning diffuser and its spatial pattern is further randomized by the second diffuser.

  • Patent number: 11644671
    Abstract: Within applications for Near-to-Eye (NR2I) displays, irrespective of whether they are for short-term, long-term, low vision, augmented reality, etc., there is a conflicting tradeoff between user comfort, ease of attachment, minimizing intrusiveness and aesthetics which must be concurrently balanced with and are often in conflict with providing an optical vision system within the NR2I display that provides the user with a wide field of view and high image resolution whilst also offering a large exit pupil for eye placement with sufficient eye clearance. Embodiments of the invention address these issues and provide a high performance optical system through the design of the optical eyepiece design to overcome these limitations within a bioptic configuration with laterally disposed displays.

An image projector includes a prism with a first surface associated with an illumination arrangement, a second surface associated with a reflective spatial light modulator (SLM), a third surface having a quarter-wave plate and a reflective collimating lens, and a fourth surface optically coupled to the coupling-in surface of the LOE. A polarizing beam splitter (PBS) is arranged within the prism to define a light path from the illumination arrangement via the SLM and the collimating lens to the coupling-in surface of the LOE. A fifth surface of the prism forms a continuation of one of the major external surfaces of the LOE.

  • Patent number: 11644681
    Abstract: A semiconductor laser shaping device includes, along the light path of a semiconductor laser, a fast axis collimating lens, slow axis collimating lens, the half wave plate, a polarization beam combining prism, and a crawling prism group. The laser emitted by the semiconductor laser is collimated by a fast-axis collimating lens and then by a slow-axis collimating lens, and subsequently injected into a half wave plate and polarization beam combining prism, which compresses its spot size along the slow axis while keeping the spot size unchanged along the fast axis. The laser beam then passes through the crawling prism group, which shifts a portion of the light in the slow-axis direction to the fast-axis direction, which again compresses the light beam in the slow-axis direction. The device can reduce the beam size of a semiconductor laser in the slow-axis direction, reducing its beam parameter product and improving beam quality.

  • Patent number: 11644682
    Abstract: A novel class of imaging systems that combines diffractive optics with 1D line sensing is disclosed. When light passes through a diffraction grating or prism, it disperses as a function of wavelength. This property is exploited to recover 2D and 3D positions from line images. A detailed image formation model and a learning-based algorithm for 2D position estimation are disclosed. The disclosure includes several extensions of the imaging system to improve the accuracy of the 2D position estimates and to expand the effective field-of-view. The invention is useful for fast passive imaging of sparse light sources, such as streetlamps, headlights at night and LED-based motion capture, and structured light 3D scanning with line illumination and line sensing.
