  • Patent number: 10310249
    Abstract: A binocular adaptor system enables quick and secure attachment of binoculars to a stand, such as a tripod stand. The binocular adaptor assembly utilizes an adaptor body that has a stand end for coupling with a stand and a clamp end for receiving a clamp. The clamp is configured to extend into a clamp aperture in the adaptor body and has a clamp pin aperture to receive a lock pin. A spring is configured between an insert end of the clamp and the adaptor body to provide a force against the insert end of the clamp. When a lock pin in inserted into the clamp aperture, the spring engages a lock stop of the clamp with an insert lock portion of the lock pin to secure the lock pin in place. A lock sleeve can then be tightened to prevent pressing of the button.

  • Patent number: 10302830
    Abstract: A wire grid device having transmission power characteristics and a power extinction ratio in a terahertz wave band that cannot be achieved conventionally. A cutout is formed between one end and an opposite end of a rectangular metal thin plate to form a plurality of grid plates each having an elongated grid part between the one end and the opposite end. The grid plates are stacked in such a manner that the grid parts of the grid plates are spaced at a given interval and face each other, thereby forming a grid plate stack. In this case, spacers are inserted between one ends and between opposite ends of adjacent ones of the grid plates to form parallel flat plates configured by the grid parts. The grid plate stack forming the parallel flat plates operates as a polarizer for a terahertz wave band.

  • Patent number: 10274660
    Abstract: A holographic substrate-guided wave-based see-through display has a microdisplay, capable of emitting light in the form of an image. The microdisplay directs its output to a holographic optical element, capable of accepting the image from the microdisplay, and capable of transmitting the light. The holographic optical element couples its output to an elongate substrate, capable of accepting the light from the holographic optical element at a first location, and transmitting the light along a length of the substrate by internal reflection to a second location, the elongate substrate being capable of transmitting the accepted light from the second location. The substrate couples out what it receives to a transparent holographic optical element, capable of accepting the light transmitted from the substrate and transmitting it to a location outside of the holographic optical element as a viewable image.

  • Patent number: 10234686
    Abstract: In a near-eye optical display system comprising a waveguide and diffractive optical elements (DOEs) configured for in-coupling, exit pupil expansion, and out-coupling, a rainbow phenomenon manifested in the display may be removed or reduced using a polarizing filter at the front of the system so that real-world/stray light entering the system has a particular polarization state, for example TM-polarized. The polarizing filter is utilized in conjunction with a downstream out-coupling DOE that includes diffractive grating structures that are configured to enable sensitivity to an opposite polarization state, for example TE-polarized. An imager is configured to produce virtual-world images that also have a TE-polarized state. The polarization-sensitive out-coupling DOE diffracts the TE-polarized imaging beam out of the grating for display while the TM-polarized light from the real world and/or stray light passes through the grating without diffraction and thus cannot contribute to rainbows in the display.
