Publication number: 20220373969Abstract: A method and system for a scalable multi-sense user experience are disclosed. A three-dimensional (“3-D”) display is disposed behind a slit plane comprising slits and ultrasonic transducers. Light from the 3-D display passes through the slits in the slit plane to generate a 3-D image. The ultrasonic transducers on the front of the slit plane, i.e., opposite the side where the 3-D display is disposed, generate directed acoustic field and/or a formed tactile field. Because the generating components for all three senses, i.e., visual, audio, and tactile, are coplanar, units may be tiled and thereby scaled to generate larger multi-sense experiences.Type: ApplicationFiled: April 20, 2022Publication date: November 24, 2022Inventor: Daniel Smalley

Patent number: 11428890Abstract: A method and system are disclosed for using circular symmetry to eliminate the angle limitations of an optical axis in a scanned aperture holography system. A Room-sized Holography System may be a scanned aperture holographic video display and may comprise a rotating platform, a telescope comprising a first lens and a second lens, and scanners at the Fourier plane where the focal length of the first lens and the second lens meet. The platform may rotate around an axis aligned with a spatial light modulator. When the platform rotates, the scanners rotate, thereby de-rotating a SAW image. The second lens may be a spherical reflective surface for redirecting light from the spatial light modulator, having passed through the first lens and reflected off a mirror-scanner, toward a user's eyes. The user may be on a chair above the spatial light modulator, wherein the chair is configured to rotate with the spatial light modulator.Type: GrantFiled: March 14, 2019Date of Patent: August 30, 2022Assignee: Brigham Young UniversityInventor: Daniel Smalley

Publication number: 20210310924Abstract: Time multiplexing an electromagnetic trap beam may be used to generate trap shapes/geometries to trap one or more particles with one electromagnetic beam by directing the electromagnetic beam at a pattern of different locations with sufficient rapidity to form an effective shape/geometry. Additionally, multiplexing an electromagnetic trap beam may be used to shutter trapping electromagnetic radiation to protect a viewer, use the same beam for multiple functions, move and organize particles, and generate illumination effects.Type: ApplicationFiled: March 15, 2021Publication date: October 7, 2021Applicant: Brigham Young UniversityInventors: Daniel Smalley, Braden Huffman, Stephen Griffith

Patent number: 11130287Abstract: A system for three-dimensional (3D) optical trap printing (OTP) comprises a first particle susceptible to being cured by a light beam, a first light source to generate a trapping light beam to trap the particle, and a second light source to generate a curing light beam to cure the first particle. Using scanning and other optics, the trapping light beam may move the first particle to a desired printing location at which the curing light beam may cure the first particle, thereby adding the first particle to a printed structure. Using OTP, structures may be printed in any orientation, with or without support structures. Additionally, OTP allows for printing composite materials, high resolution color printing, printing of complex structures without sacrificial filler material, simultaneous printing of multiple particles, and combining particles at a print location.Type: GrantFiled: January 23, 2019Date of Patent: September 28, 2021Inventor: Daniel Smalley

Patent number: 10739665Abstract: A method and system for using laser-induced structures to direct light to exit the bottom of a leaky mode device, and further to divide leaky mode light into multiple orders, and to implement one or more pulsing/strobing patterns such that a field of view is increased for a viewer, or the view zone is increased for a viewer. A leaky mode device may comprise a substrate, a surface acoustic wave (“SAW”) transducer, a waveguide having a higher refractive index than the substrate, an input region for input light, and laser induced structures such as grating. The SAW transducer may be positioned on a top surface of the substrate, and may be configured to emit a SAW wave to propagate across the substrate. The waveguide may be positioned below the SAW. The input wave region may be configured to couple light onto the waveguide.Type: GrantFiled: July 11, 2018Date of Patent: August 11, 2020Inventor: Daniel Smalley

Patent number: 10474101Abstract: A method and system for recycling signals in a leaky mode device for a holographic display or other application. A leaky mode device comprises at least a first transducer, a substrate, and a second transducer. The first transducer may be configured to receive an input signal from a signal arbiter, which forwards to the first transducer as an input signal either a new input signal or a recycled input signal (or some combination of the two). The first transducer converts the received input signal to a SAW (surface acoustic wave) and transmits the SAW through the substrate to the second transducer, which converts the received SAW to an output signal, and forwards the output signal to an amplifier, which amplifies the output signal (now a “recycled” signal) and forwards to the signal arbiter. This system facilitates persistence for points in a holographic display without the need for continually rewriting to leaky mode devices.Type: GrantFiled: April 17, 2018Date of Patent: November 12, 2019Inventor: Daniel Smalley

Patent number: 9483021Abstract: In an illustrative implementation of this invention, an animated holographic display is created as follows: Multiple HPO holograms in the shape of horizontal strips are recorded on an H2 medium. These horizontal strips are vertically displaced from each other. An animated real image is displayed by sequentially illuminating these HPO holograms. In illustrative implementations of this invention, the vertical perspective of at least some adjacent HPO stripes are identical.Type: GrantFiled: March 15, 2013Date of Patent: November 1, 2016Assignee: Massachusetts Institute of TechnologyInventors: Victor Michael Bove, Jr., Daniel Smalley, Quinn Smithwick

Publication number: 20120050833Abstract: In an illustrative implementation of this invention, an animated holographic display is created as follows: Multiple HPO holograms in the shape of horizontal strips are recorded on an H2 medium. These horizontal strips are vertically displaced from each other. An animated real image is displayed by sequentially illuminating these HPO holograms. Unless corrected, this approach causes the animated image to appear to rotate vertically. The vertical parallax rotation arises because, when recording the HPO holograms, the vertical perspectives of the various HPO holograms differ. In illustrative implementations of this invention, this vertical parallax rotation may be corrected at least three different ways: (1) the content of H1 may be pre-rotated, (2) H1, H2 or both may be translated during exposures, or (3) only a thin horizontal stripe of H1 may be illuminated during holographic transfer to eliminate vertical parallax in the real image transmitted from H1.Type: ApplicationFiled: August 30, 2010Publication date: March 1, 2012Applicant: MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Victor Michael Bove, JR., Daniel Smalley, Quinn Smithwick
