A system for simulation of a composite beam is disclosed. The system can comprise a memory storing executable instructions and one or more processors coupled to the memory to execute the executable instructions. The one or more processors can be configured to generate a representation of the original beam pattern transmitted via a propagation of the composite beam, to invoke a propagation model that represents a distortion for the propagation of the composite beam, and to determine a representation of a distorted beam pattern based on the propagation model and on the representation of the original beam pattern transmitted via the propagation.

Described herein are embodiments of fiber scanning systems and methods of scanning optical fibers. The disclosed systems and methods advantageously provide an improvement to the scanning range, the oscillation amplitude, and/or the maximum pointing angle for an optical fiber in a fiber scanning system by inducing a buckling of a portion of the optical fiber.

Various techniques are provided for implementing, operating, and manufacturing infrared imaging devices using integrated circuits. In one example, a system includes a focal plane array (FPA) integrated circuit comprising an array of infrared sensors adapted to image a scene, a plurality of active circuit components, a first metal layer disposed above and connected to the circuit components, a second metal layer disposed above the first metal layer and connected to the first metal layer, and a third metal layer disposed above the second metal layer and below the infrared sensors. The third metal layer is connected to the second metal layer and the infrared sensors. The first, second, and third metal layers are the only metal layers of the FPA between the infrared sensors and the circuit components. The first, second, and third metal layers are adapted to route signals between the circuit components and the infrared sensors.

A projection apparatus includes a projection cavity, a light source, a scanning motor, and a processor. The light source and the scanning motor are located inside the projection cavity, and the processor is connected to both the light source and the scanning motor. A reflection layer is disposed on a scanning mirror of the scanning motor, where the reflection layer is configured to reflect light emitted by the light source.

To provide an illumination device and a projection type image display device that illuminate an area to be illuminated (image formation area) under conditions where speckle noise is less noticeable. An illumination device according to the present invention includes: a light source 11 that emits coherent light; an optical scanning section 15 that scans the coherent light emitted from the light source 11; and an optical path conversion system 21 configured to allow the coherent light scanned by the optical scanning section 15 to illuminate an area to be illuminated sequentially in an overlapping manner. An incident angle of the coherent light that enters respective points of the area to be illuminated changes with time.

An example apparatus for encoding video frames includes a frame analyzer to execute a look ahead analysis on a received set of frames. The frame analyzer includes a look ahead video analyzer to down-sample the set of frames and encode the down-sampled frames with a constant quantization parameter (QP). A number of generated bits for each of the frames is used as a complexity measurement for each of the frames. The apparatus further includes an encoder to encode the input frame using an adjusted bit allocation based on a relative complexity of the input frame in relation to a complexity of the set of frames.

An approach for projecting light may be implemented using a acousto-optical depth switch that uses surface acoustic waves produced along a substrate to guide image light to different areas. The surface acoustic waves may be generated on a substrate using a transducer. Surface acoustic waves of different frequencies can guide image light onto different optical elements at different physical positions. The optical elements may be configured to show objects in an image at different distances from a viewer.
