摘要
相机采用棱镜分光,薄片管增强象,电选通分幅。由四个薄片管组成四个通道,每一个通道代表一个单幅相机,分幅时序由专门电控电路进行控制,接触相机记录图象,最短曝光时间3ns,动态空间分辩率5～81lp/mm,最高分幅速率2×10~8幅/秒,动态范围50°,在爆炸、激光、放电,光谱学等方面有广泛的应用。
This paper introduced a kind of camera adopting prism to Split light beam, Slice tube to intensity image, electrical gate to frame, four channel that compose four slice tubes, each channel can be a single picture camera. The temporal order of framing image is controlled by the special electricical circuitry. Image is recorded by means of contact camera. The shortest exposure time is 3ns. The dynamical spatial resolusion is 5- 81p/ mm. The highest framing rate is 2× 108 frames/sec. The dynamic range is 50 x. This product can be used in the explosion, laser, discharge, spectroscope, etc.
