从电视荧光屏、电子显微镜、计算机输出端以及各种示波器的阴极射线管拍摄图像或波形,在科研和生产上应用愈来愈广泛。它能记录下宝贵的形像资料,特别是肉眼根本看不见或无法辨认的过程与现象,对分析研究这类过程与现象具有特殊意义。例如拍摄监视器接收到的宇宙飞船发回地面的其他星球照片;探测器检知的人类无法接近的目标信息;以及声波振动、光随时间变化等现象,都是很有价值的特种照相应用。 From television screens, electron microscopes, computer output and a variety of oscilloscope cathode ray tube to capture images or waveforms, research and production more and more widely used. It can record precious image data, especially the invisible or unidentifiable process and phenomenon with the naked eye, which has special significance for analyzing and studying such processes and phenomena. For example, taking pictures of other planets sent back to the ground by a spacecraft that is received by a monitor; target inaccessible information that human beings detect by a detector; and acoustic vibration and light changes over time are all valuable special camera applications.
