  • Patent number: 10365476
    Abstract: Mirror control circuitry described herein is for controlling a first micro-mirror of a micro-mirror apparatus that scans across a target area in a scan pattern. The mirror control circuitry includes a processor that determines a mechanical angle of the first micro-mirror for a given instant in time during scanning of the first micro-mirror between upper and lower rotational limits, the mechanical angle being such to maintain the scan pattern as being uniform while the micro-mirror apparatus scans across the target area between the upper and lower rotational limits. The processor also generates a driving signal for the first micro-mirror as a function of the determined mechanical angle for the first micro-mirror at the given instant in time.

  • Patent number: 10365492
    Abstract: Systems, devices, and methods for beam combining are described. A monolithic beam combiner includes a solid volume of optically transparent material having two orthogonally positioned planar input surfaces, an output surface, and at least two planar dichroic reflectors positioned within the solid volume. Multiple light sources input light into the solid volume through the two planar input surfaces such that each light beam from a respective source is initially incident on one of the planar dichroic reflectors. The light is reflected by and transmitted through the reflectors and an aggregate beam is created. Because the reflectors are within an optically transparent material the beam combiner can be made more compact than a conventional beam combiner. This monolithic beam combiner is particularly well suited for use laser projectors and in wearable heads-up displays that employ laser projectors.

  • Patent number: 10345598
    Abstract: An image combiner, also referred to as a combiner optic, of a near-eye display system or the like transmits enough light so a user can see remote objects in a “world view”, while also reflecting enough light so the user can simultaneously see a projected image in a “projected” (augmented) view. The disclosed image combiners use two partial reflectors configured to form a wedged reflective cavity. In the display system, light from an imaging device follows a path to the user's eye that includes three reflections in the wedged cavity. By using this capability of the wedged cavity, the combiner optic can have a substantially reduced thickness, and lower profile, than a combiner optic that uses only one partial reflector and only one reflection in the optical path.

  • Patent number: 10338282
    Abstract: Tooling and optic elements for a retro-imaging system may be formed on order near atomic level of accuracy by making use of either etching or growth techniques of a cubic crystal lattice, such as silicon. The elements may be formed directly using selective etching or epitaxial growth by coating and clear resin lamination, or replicated to avoid shrinkage and curvature by use of low shrinkage resins or double-fill molding techniques. Through the use of these highly accurate reflection/diffraction elements, floating images may be formed with relatively high resolution in retro-reflective imaging systems, for example.

  • Patent number: 10302942
    Abstract: A light-source device including a light-emitting element to emit light, a light-receiving system, an acquisition unit, a setting unit, and an adjuster. The light-receiving system receives the light emitted from the light emitting element. The acquisition unit acquires a wavelength of the light emitted from the light emitting element. The setting unit sets a target value of an amount of the light received by the light-receiving system based on the wavelength acquired by the acquisition unit. The adjuster adjusts an amount of the light emitted from the light emitting element such that the amount of the light reaches the target value of the light that is set with the setting unit.

  • Patent number: 10295815
    Abstract: Various examples are provided related to imaging with augmented stereoscopic microscopes. In one example, an augmented stereoscopic microscope includes an objective lens that can simultaneously receive near infrared (NIR) images and visible bright-field images of an examined object and an augmentation module. The augmentation module can separate the NIR images from the visible bright-field images for processing by an image processing unit to produce synthetic images using the NIR images and combine the synthetic images with the visible bright-field images to form co-registered augmented images that are directed to an eyepiece of the augmented stereoscopic microscope. In another example, a method includes obtaining a NIR image of an examined object; generating a synthetic image using the NIR image; combining the synthetic image with a real-time visual image of the examined object to form an augmented image; and directing the augmented image to an eyepiece of an augmented stereoscopic microscope.

  • Patent number: 10295816
    Abstract: A surgical microscope employs a pentaprism beam splitter as a branching unit to branch each beam passed through variable power optical systems into a first beam and a second beam, the first beam being horizontally reflected for an eyepiece unit, the second beam being vertically transmitted for an imaging device. The pentaprism alone is capable of simultaneously conducting reflection to provide an erect image and transmission to provide a photographing image, thereby reducing the number of optical parts in a microscope body of the surgical microscope.
