频闪多幅高速显微摄影设备

A STROBOFLASH MULTIIMAGE HIGH SPEED MICROGRAPHY EQUIPMENT

介绍了一种拍摄高速运动中微小物体的频闪多幅高速显微摄影设备。这是一种特殊的空间立体交叉4路间歇而连续闪光照明和相应的4组各自独立的显微照相系统组成的装置。显微照相系统具有拍摄工作距离长，照相分辨率高等特点，能将同一目标物经4组独立的光学系统分别成像于同一照相底片的4个家限内。由于所采用的4路独立的火花闪光光源照明闪光脉冲时间短，亮度高，因此能在瞬间“冻结”高速运动的物体，与显微照相系统配合，捕捉运动中的物体，获得4幅不同时刻的清晰照片。通过对4幅照片的测量、分析，可研究物体运动规律和轨迹以及精确测得物体的大小。用该装置已成功地拍摄了高速运动中雾化状态下水粒子的运动状态、分布。

A stroboflash multiimage hish speed microsraphy equipment has been introduced. The equipment can photograph small moving objects, and is composed of a special three-dimensional lighting system and four independent microphotograph systems. The lighting system can illuminate internally and continuously in four paths.The system has many advantages, viz., a long photograph distance, high resolving power, and the same object can be imaged in four quadrants of a negative through four independent optical systems. The use of four independent spark flash sources having short flash phase time and high brilliance, high speed moving objects can be' stopped'instantaneously in cooperation with the microphotograph system, a moving object can be photographed giving four photographs at different moments of time. By measurement and analysis of the four photographs, the movements and locus of the object can be studied and the dimention of the object can be measured. This equipment has successfully photographed the moving state and dispersion of water particles moving at high speed.
