Abstract: A display method and system are disclosed for virtual/augmented reality. The method includes the steps of generating an image by a projection engine and projecting light rays defining the image onto a diffuser holographic optical element (DHOE) located between an observer and a concave mirror element, where a concave surface of the concave mirror element faces the observer. The light rays are projected onto the DHOE at a reference angle that causes the light rays to be diffused to the concave surface of the concave mirror element and the diffused light rays are reflected back to the observer such that the observer perceives a virtual image that appears to the observer at a position behind the concave mirror element and further from the observer than the concave mirror element.

Abstract: The present invention employs a beam steering apparatus to isolate valuable cells from other cells, tissues, and contaminants. In one embodiment, the system balances optical trapping against biasing flow to parallelize cell sorting under the flexible control of computer program-directed traps which differentially manipulate cells based on their composition or labels to direct separation.

Abstract: Our invention relates generally to an optical switch (31) and an optical router (10) to rapidly route signals from particular channels (22, 24) within an optical band by using optical switches (20) which utilize a controlled whispering gallery mode (WGM) resonance of dielectric microspheres (S1, S2, S3) to optically switch signals. Another invention relates to optical filters which use a WGM resonate structure (150) to isolate and switch specific optical signals between waveguides (F1, F2). In other inventions, the filter (100) is switched “on/off” by signal loss within a WGM resonate structure (150) which disrupts the WGM resonance; the filter (100) isolates and switches a specific wavelength signal from among a group of signals of different wavelengths; and is switched “off” by adjusting the index of refraction of the resonate structure to become substantially similar to the index of refraction of the surrounding medium.

Abstract: The present invention relates generally to an apparatus and method to generating and controlling optical traps for manipulation of small particles. An upstream modification of an input laser beam provides a beam with a square or other preselected, cross section of intensity which can be used to form optical traps with a corresponding cross section of intensity.

Abstract: The present invention relates to a system of applying optical gradient forces to form a plurality of optical traps to manipulate small particles. The system includes a light source for generating a focused beam of light which is directed along an optical axis though a phase patterning optical element having a variable optical surface and which has a virtual lens encoded thereon. The optical element produces a plurality of beamlets that are coverged at a position between the optical element and a single transfer lens, and directed through the transfer lens to overlap at the back aperture of a focusing lens. The focusing lens coverges the beamlets to form a plurality of optical traps in the working focal region where particles to be examined, manipulated, or measured, are disposed.

Abstract: The present invention relates generally to generating and controlling optical trap arrays for manipulating particles. In particular, the invention relates to a dual function optical element able to both diffract laser light into beamlets and converge the beamlets (acting as a virtual lens for laser light), thereby eliminating the need for multiple physical lenses to transfer the diffracted laser beams to a focusing lens. The invention also relates to improved monitoring or optical traps by limiting the amount of noise reflected and scattered resulting from un-diffracted, laser light.

The probes are contained within optical traps which allows for alterations in the selection and re-configuration of the quantity or quality of probes in the array. Moreover, the array is dynamic in that once configured the optical traps may allow for independent repositioning of a given optical trap and contained probe.
