    摘要： Apparatus, for detecting at least one object and preventing receiver burn-out, mounted on a vehicle, including a laser and at least one receiver, the receiver being coupled with the laser, the laser for transmitting a beam of light and the receiver for detecting reflections of the beam of light from the object, the laser including at least one signal diode, a commutator, a power supply signal diode driver, a circulator, an erbium doped fiber (EDF), a wavelength division multiplexer (WDM), a narrow band Bragg reflector, a first fiber pump diode, an output combiner and a second fiber pump diode, the commutator being coupled with each signal diode and the power supply signal diode drive, the circulator being optically coupled with each signal diode, the EDF and the output combiner, the WDM being optically coupled with the EDF, the narrow band Bragg reflector and the first fiber pump diode and the second fiber pump diode being optically coupled with the output combiner, each signal diode generating a beam of light distinct from one another, the power supply signal diode driver for supplying energy to each signal diode, the circulator for directing the beam of light in at least one of at least two different directions, the EDF for amplifying the beam of light thereby producing an amplified beam of light, the narrow band Bragg reflector for reflecting only the amplified beam of light through the EDF a second time, thereby producing a double amplified beam of light and the first fiber pump diode and the second fiber pump diode for pumping the EDF, wherein the WDM and each of the signal diodes are located on opposite sides of the EDF, wherein the output combiner outputs the beam of light, wherein the commutator enables each signal diode, one at a time, to draw a predetermined amount of energy from the power supply signal diode driver, wherein one signal diode generates a low energy beam of light and another one generates a high energy beam of light, wherein the low energy beam of light is transmitted by the output combiner before the high energy beam of light, and when the low energy beam of light is detected by the receiver, and the energy level of the low energy beam is above a predetermined threshold, the high energy beam of light is not transmitted.

    摘要： There is provided a method for non-scanning multi-pixel ranging of a scene, comprising the steps of providing a single detector/receiver associated with a time-delay arrangement, producing a time-arrival distribution of pulse echoes of at least part of a remote scene in a defined ranging plane, receiving said distribution as produced on the ranging plane and conveying it, echo pulse by echo pulse through a plurality of echo pulse conveying means to the single detector/receiver, while introducing a time delay, whereby the echo pulses arrive at the single detector/receiver in a sequential order, and using an electronic logic to reconstruct the time-arrival distribution from the time-delayed echo pulses received by the detector/receiver. Systems for ranging of a scene are also provided.
