英国的变像管相机目前在国际上处于领先地位。它不仅具有一支高水平的研究队伍,而且有几个世界驰名的生产变像管和变像管相机的公司。世界上第一台变像管相机就是由英国人J.S.Courtney—Pratt于1949年研制成功的。50年代英国电子管公司仿制了苏联的PIM变像管,后来称之为P856。这为变像管相机在英国的发展奠定了基础。以后的微微秒变像管PHOTOCHRONI和PHOTOCHRONⅡ均是在此基础上改进而成的。60年代EMI公司研制成功了四级磁聚焦像增强器。又由于Huston
The British change tube camera is currently in the international leader. It not only has a high-level research team, but also has several of the world’s most famous companies producing tube and tube cameras. The world’s first tube camera was developed by the British J.S. Courtney-Pratt in 1949. In the 1950s, the British tube company imitated the Soviet Union’s PIM image tube, which was later called the P856. This laid the groundwork for the development of the tube camera in the United Kingdom. Subsecond picosecond PHOTOCHRONI and PHOTOCHRON Ⅱ are improved on this basis. Sixty EMI company successfully developed four magnetic focus image intensifier. And because of Huston
