    • In a system of real-time coherent optical filtering of visual imagery which encompasses a laser and a set of lenses for transmitting a visual target image of an input, a Fabry-Perot interferometer for filtering the target image to produce a filtered target image at an output having a predetermined bandwidth of spatial frequency information, the improvements relate to transmitting and original unfiltered image to the output for overlaying the filtered image for spatial enhancement of the predetermined spatial frequency bandwidth of information in the filtered image, and flickering the filtered image to achieve temporal enhancement of the visual information in the spatial frequency bandwidth of interest.
    • 在包括用于传输输入的视觉目标图像的激光器和一组透镜的视觉图像的实时相干光学滤波系统中,用于对目标图像进行滤波以产生滤波的目标图像的法布里 - 珀罗干涉仪 输出具有空间频率信息的预定带宽,所述改进涉及将发射和原始未滤波图像输出到输出,以覆盖滤波图像以用于滤波图像中信息的预定空间频率带宽的空间增强,并且使滤波图像闪烁以实现 在感兴趣的空间频带中视觉信息的时间增强。
