摘要
研究照相机近摄原理及实现近摄的各种方法,针对课题“红外报警照相系统”的要求,运用延伸像距和缩短焦距的方法,对变像管荧光屏的近摄进行探讨和尝试,提出荧光屏进摄的规范.
The principle and the implementation on the close-up photography has been studied. In accordance with the reguirement of the topic 'Infrared Alarm Camera System', the close-up photography to fluorescent screen of image converter has been investigated by using stretching the imape distance and reducing the focal distance. In conclusion, We propose a standard of the clOSe-up photography to fluorescent screens.
