摘要： A night vision system for a vehicle is provided. The system includes an illumination subsystem for illuminating a region proximate the vehicle, a receiver for receiving light reflected off objects in the illuminated region and generating a signal responsive to the received light. A GPS unit is included in operative communication with a GPS network for generating a time signal and vehicle directional data. A controller is programmed to periodically pulse on the illuminating device and the receiver substantially simultaneously as a function of the time signal and the vehicle directional data. In particular, vehicles traveling in opposite directions will have their night vision system activated out-of-phase with each other so that neither night vision system is nullblindednull by illumination emitting from the other.

摘要： A light coupling apparatus for coupling a linear diode laser array to an optical fiber. The apparatus includes a cylindrical lens positioned adjacent and substantially parallel to the linear diode laser array. The cylindrical lens has a length substantially equal to the length of the linear diode laser array, and receives emitted light from the plurality of diode lasers within the linear diode laser array to collimate the light. The collimated light is received by a wedge-shaped coupling element between the cylindrical lens and the optical fiber. The coupling element has a length (L) extending from an input surface to an output surface. The input surface defines a radius of curvature along a height (h) that is substantially equal to the cylindrical lens length. The coupling element tapers from its input surface to its output surface. The input surface also has an associated width (w1), and the output surface has an associated width (w2). The input surface width is substantially equal to a diameter of the cylindrical lens, and the output surface width is substantially equal to a diameter of the input end of the optical fiber.

摘要： A lighting system for night vision applications including a near infrared light source, a visible light source, a beamsplitter and an optical element. The beamsplitter is arranged to reflect light emitting from either the near infrared light source or the visible light source and transmit light emitting from the other of the near infrared light source or visible light source so as to produce a color-corrected light source. The optical element is disposed a predetermined distance from the color-corrected light source. The optical element includes an input surface for receiving light from the color-corrected light source and an output surface for emitting the received light in a desired emission pattern. In one embodiment, each of the near infrared light source and visible light source is associated with respective first and second optical elements. The first and second optical elements are arranged such that the emission patterns of each optical element are substantially identical and overlapping to form a single color-corrected light emission pattern.

摘要： A method of detecting objects with a night vision system is provided. The night vision system includes a light source and a camera. The method includes activating the light source as a sequence of light pulses wherein each light pulse is increasing in intensity for a predetermined number of pulses to form a pulse train. The camera is activated as a corresponding sequence of detection windows wherein each of the windows corresponds to one of the light pulses for receiving reflected light resulting from the corresponding light pulse. The light pulses and detection windows are configured such that a time delay between each corresponding light pulse and detection window is increasing throughout the pulse train. In another variation, the camera gain is increased throughout the pulse train. In yet another variation, the light pulses have constant amplitude, the camera gain is constant for all pulses, and the number of camera gain windows increases as the delay increases. In all cases, objects nearer the night vision system are imaged with lower intensity light, less camera gain, and/or fewer laser pulses than objects further away to provide a composite image in which the apparent brightness of near and far objects can be controlled.
