Abstract:
A method and system for reducing speckle in an image produced from a coherent source of radiation is provided. The method includes coupling a source beam received from a coherent optical source into an optical fiber. A position of at least a portion of the fiber may be modulated using a ditherer. The source beam may be refracted by a lens after it is decoupled from the optical fiber, such that the source beam is aimed at a microlens diffuser. In accordance with a particular embodiment, the source beam may be projected from the microlens diffuser onto a spatial modulator. The spatial modulator may be positioned to project the source beam via an imaging lens, to a target.

Abstract:
An apparatus and method by which an image is projected to pupils of a viewer. Preferably, the image covers only areas occupied by the pupils and tracks the areas occupied by the pupils such as to provide continuous display of the imagery to a viewer. The method is to dynamically control the direction of light into sub-apertures selected by a tracking device. By imaging selectively into the sub-apertures where the pupils are temporally located instead of imaging into a generally large area, the disclosed apparatus is power efficient and exclusive because the projected images are covert. This method is applicable to most biocular displays, for instance, but not limited to “see through” systems, which overlay imagery over real world scenes and where geometrically precise projection is critical. In one embodiment, the pupil scan apparatus is combined with a retinal scan apparatus to provide security. In this manner, only an authorized user of the apparatus can operate it.

Abstract:
In accordance with one embodiment of the present disclosure, a system comprises a projection system. The system further includes an image generator disposed in the projection system. The image generator is operable to generate a plurality of rays. The system further includes an objective lens disposed in the projection system. The objective lens is operable to refract the plurality of rays. The system further includes a component operable to reflect the refracted rays onto a target in order to form an image. The image is operable to be moved in relation to the target. The movement of the image is independent of any displacement of the projection system in relation to the target.

US Classification:
353 20, 35948908
Abstract:
In accordance with one embodiment of the present disclosure, a system may include a polarizing beamsplitter for splitting one or more unpolarized rays received from an illumination source into a first polarized component and a second polarized component, the first polarized component and the second polarized component having orthogonal polarizations to each other. The system may also include a half-wave plate for rotating the second polarized component to the same polarization as the first polarized component. The system may further include a lens group for passing the first polarized component to a target plane as a first polarized ray, and further for separately passing the second polarized component to the target plane as a second polarized ray.

Abstract:
An improved device and system for facilitating polymerase chain reaction including a light source, detector, waveguide, and filters that occupy minimal space and facilitate detection of stationary samples, reduced sample read time, and simultaneous reading of multiple light wavelengths.
Provided are methods and systems for concurrent imaging at multiple wavelengths. In one aspect, a hyperspectral/multispectral imaging device includes a lens configured to receive light backscattered by an object, a plurality of photo-sensors, a plurality of bandpass filters covering respective photo-sensors, where each bandpass filter is configured to allow a different respective spectral band to pass through the filter, and a plurality of beam splitters in optical communication with the lens and the photo-sensors, where each beam splitter splits the light received by the lens into a plurality of optical paths, each path configured to direct light to a corresponding photo-sensor through the bandpass filter corresponding to the respective photo-sensor.
