摘要
本文介绍了间歇式、棱镜补偿式、转镜高速摄影机和判读仪的新进展,也涉及到十八届国际高速摄影与光子学会议展览会的部分内容。
The articles concerned with high speed cameras in 18th ICHSPP are outlined in this paper.The main characteritsics and applications of high speed cameras which involved intermitting cameras, prism-rotating cameras and mirror-rotating cameras in USSR and other countries are introduced. Some developments in optical design, driving methods and spectral converage of photography have been achieved. The methods of increasing effectiveness of rotating-mirror framing and streak cameras are analysed In 3-D high speed photography, several cameras can be synchronized by using a photoelectric optimum oscillator.In China, the high-strength aluminium mirror was used in ZDF-180 waiting framing camera. Its framing rate is from 1×104-180×104 fps. In order to realize automation and intellectual faculties in cameras, the cameras controlled by microprocessor control console are used, it can run in the mode combined with assembly program. By using the detector of dynamic image-quality, the dynamic resolution concerned with mirror deformation in high speed can be examined with eyes. There are also some developments in synchronizing cameras, increasing luminosity and improving structure of cameras.In addition, some kinds of apparatus in film motion analysis are displayed in the exhibition of the congress. Their methods of measurement and characteristics are introduced.
