Abstract: An emissive panel display comprising an array of microLEDs for producing pixels for images in a projection display system is configured with an array of microlenses in which each microlens in the array corresponds to a respective pixel on the panel display. The configuration of the microlenses varies based on their distance in the plane of the panel display from a central projected axis. Microlenses may be configured with surfaces that are optimized to improve optical efficiency. To improve display illumination uniformity, a microlens may be configured to manipulate the emission angular profile for a given pixel over a wide range to match its chief ray angle (CRA), in which the chief ray for the pixel passes through a center of an entrance pupil of projection optics in the display system.

Abstract: An imaging system for cell-based therapies is provided. The imagining system includes one or more optical tags configured for insertion into a cell or biological tissue, an excitation light source configured to illuminate the one or more optical tags; a detector configured to measure optical emission of the one or more optical tags; an imaging subsystem configured to determine a three-dimensional location of each of the one or more optical tags in the cell or biological tissue; and a controller in electrical communication with the excitation light source, the detector, and the imaging subsystem. Each of the one or more optical tags has a contrasting feature and includes a fluorescent material. The contrasting feature may be defined by at least one of a refractive index, shape, color, and laser emission of each optical tag of the one or more optical tags.

Abstract: A laser whose emission is modulated by ultrasound is presented. The laser is usually micron-sized. In response to ultra-sound modulation, the laser emission increases and decreases. Such a change in emission can be detected by external optical detectors. This type of laser can be used as a new type of imaging modality, in which laser emission in combination with sound waves or ultra-sound waves, is used for imaging Laser emission has a much narrower spectral linewidth and stronger intensity than fluorescence and therefore is able to achieve higher sensitivity, whereas sound waves are used to provide a better spatial resolution of the laser emission from the laser. In ultrasound modulated laser based imaging, multiple lasers can be placed inside cells or tissues.
