Luckoff Display Corporation - Columbus OH

International Classification:

G03H 100

US Classification:

359 15, 359 1, 359567, 362806

Abstract:

Disclosed is a curved surface element (e. g. , light bulb, ornament, light pipe, etc. ) which has at least a portion thereof (inner or outer surface) covered with a holographic diffraction grating which was constructed to be essentially distortion free on said curved surface, whereby such diffraction grating diffracts light to emit color to the observer. The diffraction grating can take for form of a holographic optical element (HOE) attached to the curved surface or a diffractive holographic optical pattern (HOP) embossed into the curved surface.

International Classification:

US Classification:

359 18, 15567, 15569, 15615, 15 17

Abstract:

The present invention is directed to an improvement in a diffractive display suitable for presenting graphic and the like displays. Broadly, a novel embodiment is realized from a holographic diffraction pattern carried by a magnet or element and an electrically energizable coil magnetically coupled with said magnet that is energizable for movement of the magnet. Rotation of the holographic diffraction pattern generates a display using the diffracted light from the holographic diffraction grating. Another novel embodiment is realized from a faceted rotatable element (FRE) having an array of facets each bearing a diffraction grating and a source energizable for rotation of the FRE from a resting station to a viewing station. Rotation of the FRE generates a display using the diffracted light from the diffraction gratings.

International Classification:

G02C 7/04

US Classification:

351162, 351165, 351177

Abstract:

A contact lens has an inner surface adapted to be placed against the eye of a wearer and an outer surface bearing a cosmetic holographic optical diffraction grating that, when worn by a wearer, displays color to an observer of the contact lens. The holographic optical diffraction grating can diffract incident light to display one or more colors to the observer, or can be formed as an alphanumeric character(s) or graphic display to the observer.

International Classification:

G01J 3/28
G01J 3/06

US Classification:

356328, 356308, 356334

Abstract:

The present invention is directed to apparatus and method for measuring the spectral characteristics of an object surface. The apparatus comprises a light source for generating an input signal comprising a plurality of wavelengths of energy and a diffraction grating for diffracting the input signal into a plurality of diffracted wavelengths of energy. A resonant mirror assembly associated with the diffraction grating sequentially directs a select diffracted wavelength to the object surface to generate a corresponding reflected wavelength of energy. The apparatus further comprises a sensor for determining each select diffracted wavelength of energy directed to the object surface and a detector for detecting one or more of the reflected wavelengths. The detector is coupled with the sensor for associating each select diffracted wavelength with each corresponding reflected wavelength.

Abstract:

The present invention is directed to method and apparatus for measuring the spectral characteristics of an object from a formed object generated input signal. The method comprises the steps of directing the input signal onto a diffraction grating. Diffracted signals are directed to a resonant mirror assembly for sequentially focusing a select diffracted signal. From that focused select diffracted signal, a spectral characteristic of said object is determined. Each said spectral characteristic is associated with each corresponding focused select diffracted signal and the associated signals are published. The apparatus is an improved spectrometer comprising a fiber cable assembly for receiving an object generated input signal and a diffraction grating. A resonant mirror assembly sequentially focuses a select diffracted signal, a sensor sensing which diffracted signal has been focused from the diffraction grating. An analyzer coupled with the sensor determines a spectral characteristic of the object from said select diffracted signal.

US Classification:

359224

Abstract:

Compact scanning techniques that can scan a large degree optical solid angle are disclosed. One particular embodiment is a processor controlled scanner that is capable of a large degree optical solid scan angle. Dual axis scan capability can be provided with a single compact package. A pivoting ball joint on which a mirror assembly is attached is employed. The mirror assembly is operatively coupled to an actuator assembly (e. g. , electro-magnets or piezoelectric based actuators). When control voltage is applied to the actuator assembly, the ball joint to moves thereby moving the integrally attached mirror assembly.

Abstract:

A projector of multiple skewed light planes or sheets is located adjacent a vehicle to be protected and detectors are arranged to detect the penetration of the light sheets by an incoming object, with the time intervals between the piercing of the planes defining the path of the incoming object and its expected impact time. An array of bullet-firing barrels is arranged to project bullets in an iron curtain under control of a fire control module that fires a round in a barrel above the projected flight path such that the round impacts the nose of the object and disables it. It is thus the piercing of the skewed light sheets that provides information as to the impact point of the object as well as its time of arrival so that a round can be fired to intercept the object as it arrives at the iron curtain.
