    • A laser warning receiver (LWR) having an ability to not only detect a low power level laser source, such as a pulse train emitted by a laser beam rider, but to also provide a high angular resolution in determining the angle of arrival of that pulse train. The receiver includes a lens/filter arrangement for a large area photodetector to detect an incoming signal from an emitting source and a high gain amplifier to amplify the signal which is then applied to a synchronization generator that generates a digital pulse train with pulses corresponding to peaks in the incoming signal. The digital pulse train is applied to a code breaker where the code is analyzed and a further code is generated anticipating the arrival of further pulses in order to verify the code. That further code is applied to a time gate generator which generate a code, synchronized with the incoming signal, that controls the high voltage of a gated image intensifier which is coupled to a video camera. Gating of the image intensifier is synchronized, as a result, with coded emissions from the source so that a video image from the camera can be displayed on a monitor and more easily differentiated from the background. The width of pulses generated by the time gate generator, the video camera, gain of the gated image intensifier, gain of the gated image intensifier and an auto-iris zoom lens coupled to the image intensifier are all under the control of a video processor.

    • An opto-electronic device for detecting a beam of radiation and determining the angle-of-arrival of that beam with a high degree of angular resolution. The device has a linear array of radiation detectors arranged in a plane with a shadow mask located at a predetermined height h above and parallel to that plane wherein the shadow mask has a plurality of transparent apertures separated by opaque areas. Each radiation detector in the array comprises at least one pair of individual detector elements and apertures of the shadow mask, which apertures have the same width as the detector elements, are centred directly above the area between adjacent detector elements. Signals generated by corresponding detector elements in each radiation detector are supplied, in parallel, to one channel providing a number of output channels which correspond to the number of individual detector elements in each radiation detector. The angle-of-arrival of a radiation beam emitted by a source and traversing the apertures can then be determined by output signals from the channels. This radiation beam detecting device is particularly designed for use in Laser Warning Receivers which detect, identify and locate laser sources associated with laser guided weapons.
    • 一种用于检测辐射束并以高度角度分辨率确定该光束的到达角度的光电装置。 该装置具有布置在平面中的辐射检测器的线性阵列,其中荫罩位于预定高度h并且平行于该平面,其中荫罩具有由不透明区域分开的多个透明孔。 阵列中的每个辐射检测器包括至少一对单独的检测器元件和荫罩的孔,这些孔具有与检测器元件相同的宽度,它们位于相邻检测器元件之间的区域的正上方。 由每个辐射检测器中的相应检测器元件产生的信号并联地提供给一个通道,其提供与每个辐射检测器中的各个检测器元件的数量相对应的多个输出通道。 然后可以通过来自通道的输出信号确定由源发射并穿过孔的辐射束的到达角度。 该辐射束检测装置特别设计用于检测,识别和定位与激光制导武器相关的激光源的激光警报接收器。
