    摘要: An imaging system includes first and second imaging arrays separated by a fixed distance, first and second drivers, and a modulated light source. The first imaging array includes a plurality of phase-responsive pixels distributed among a plurality of intensity-responsive pixels; the modulated light source is configured to emit modulated light in a field of view of the first imaging array. The first driver is configured to modulate the light output from the modulated light source and synchronously control charge collection from the phase-responsive pixels. The second driver is configured to recognize positional disparity between the intensity-responsive pixels of the first imaging array and corresponding intensity-responsive pixels of the second imaging array.

    摘要: A depth-sensing method for a time-of-flight depth camera includes irradiating a subject with pulsed light of spatially alternating bright and dark features, and receiving the pulsed light reflected back from the subject onto an array of pixels. At each pixel of the array, a signal is presented that depends on distance from the depth camera to the subject locus imaged onto that pixel. In this method, the subject is mapped based on the signal from pixels that image subject loci directly irradiated by the bright features, while omitting or weighting negatively the signal from pixels that image subject loci under the dark features.

    摘要: A semiconductor, room-temperature, electrically excited, two-photon device with thick optically active layer is provided. The intrinsic AlGaAs active layer is sandwiched between two intrinsic graded waveguide layers having increased aluminum concentration at increased distance from the active layer. The waveguide structure is sandwiched between two cladding layers of high aluminum concentration, n and p doped respectively. The structure is epitaxially grown on a substrate and further comprises other layers such as buffer, graded layers and contact layers. An etched ridge provides lateral confinement for light. The device provides two-photons gain and may be used in light sources, optical amplifiers, pulse compressors and lasers.

    摘要: Reduction in interference between different time of flight (ToF) cameras used for depth measurements and operating in the same application environment is achieved using a spread spectrum technique in which the cyclical operations of a pulsed light source such as a laser or light emitting diode (LED) and gated image sensor are varied in a pseudo-random manner in each camera. In an alternative embodiment, spread spectrum logic is applied in a ToF camera that employs phase modulation techniques.

    摘要: There is provided a new architecture for all-optical logic architecture. In this architecture the gate is partitioned into a linear front-end followed by a nonlinear back-end. The logic calculation is practically performed within the linear stage, easing the requirements placed on the non-linear part and thus reducing the gate complexity. The new structures provide flexibility and improved performance for the all-optical logic. The proposed scheme may be integrated optics/electronics. An important additional attribute of our all-optical logic family is reconfigurability, i.e. the ability of the hardware architecture or devices to rapidly alter the functionalities of its components and the interconnection between them as needed.
