摘要： A device for phase distortion compensation across an optical beam is provided. The device is a part of an optical receiver, which can be used in free space optical communications, remote sensing, optical imaging and others. 2M inputs of the combiner interfere with each other via a system of tunable coupled waveguides. The phases in interleaved waveguides of the combiner are adjusted to maximize the resulting output signal. The combiner may be used for coherent communication in combination with a balanced 90° hybrid. Integrated solutions for the proposed device are provided.

The system includes a compact transceiver chip sending optical signals in three optical fibers that encompass the monitored structure appropriately. The system contains a sequence of loops, wherein the first and the second fiber forming the loop clockwise, while the third fiber is winded along the same loop counterclockwise. A set of two detectors registers the returning signals, and a time delay between those signals is calculated, which is indicative of the disturbance event location. The event location is determined with different sensitivity in different parts of the monitored structure depending on the density of fibers in these parts.

摘要： This invention discloses an optical object tracking method and system with to up to six degrees of freedom: three translational and three angular coordinates. In the preferred embodiment, the system includes two near-infra-red light sources (e.g., light emitting diode), two cameras, and a digital signal processor. The system performs to tasks: object locking and tracking. For object locking and tracking, a single camera and two off-axis light sources are engaged. For more precise object tracking, two spatially-separate cameras and a single diode are used. In another embodiment, a third camera may be used to separate the locking and tracking tasks. The light sources may have different light wavelengths and may operate in a sequential mode. The cameras may be sensitive over different spectral ranges and may also differ in terms of field-of-view and resolution. The invention describes a method based on capturing images of light reflections at the camera focal plane and analyzing them, through mathematical mapping, for known locations of light sources and cameras. Invention can be adopted for the tracking of an eyeball. The related method determines an object location and orientation or a gaze vector and a point-of-regard.
