    摘要： A night vision system for a vehicle includes a pulsed light source for illuminating a region proximate the vehicle and a secondary trigger light source operating at a predetermined pulse timing and second wavelength. A light sensor detects light at the second wavelength. The trigger light pulses are used to indicate the pulse timing of each respective vehicle's primary NIR light source. Upon detecting another vehicle's trigger light source, the controller adjusts the pulse phase of the first light source to be exactly out-of-phase with that of the oncoming vehicle since the pulsed timing of the oncoming vehicle's NIR light source is known upon detection of the opposing vehicle's trigger light source. Each vehicle can then adjust its primary light source to be out-of-phase with the other vehicle and, hence, non-interfering.

    摘要： A laser range signal-processing device comprises a timing interval generator, a microprocessor unit, a programmable delay unit, a laser transmitter, a laser receiver, a high gain amplifier circuit and a memory. A signal-processing method of the laser range finder includes a first step in which the measurement block number and the laser emission time are set up. Thereafter, the sampling of the laser reflection signal of each block is done in sequence so as to determine a block in which an object is located. A laser beam of a predetermined delay time is emitted to the block in which the object is located. The reflective laser signals are sampled and processed to attain a precise distance between the laser range finder and the object.

    摘要： The present invention is directed to methods and apparatuses for performing temporal scanning using ultra-short pulsewidth lasers in which only minimal (micro-scale) mechanical movement is required. The invention also relates to methods for obtaining high-accuracy timing calibration, on the order of femtoseconds. A dual laser system is disclosed in which the cavity of one or more of the lasers is dithered, by using a piezoelectric element. A Fabry-Perot etalon is used to generate a sequence of timing pulses used in conjunction with a laser beam produced by the laser having the dithered laser cavity. A correlator correlates a laser pulse from one of the lasers with the sequence of timing pulses to produce a calibrated time scale. The methods and apparatuses of the present invention are applicable to many applications requiring rapid scanning and time calibration, including, but not limited to metrology, characterization of charge dynamics in semiconductors, electro-optic testing of ultrafast electronic and optoelectronic devices, optical time domain reflectometry, and electro-optic sampling oscilloscopes.

    摘要： Apparatus for creating an image indicating distances to objects in a scene, comprising: a modulated source of radiation, having a first modulation function, which directs radiation toward a scene; a detector, which detects radiation reflected from the scene, modulated by a second modulation function, and generates, responsive to said detected modulated radiation, signals responsive to the distance to regions of the scene; a processor, which receives signals from the detector and forms an image, based on the signals, having an intensity value distribution indicative of the distance of objects from the apparatus; and a controller, which varies at least one of the first and second modulation functions, responsive to the intensity value distribution of the image formed by the processor.
