红外探测器法国少数公司,特别是SAT公司(法国电讯股份有限公司),在红外探测器方面水平很高。1970年,SAT只有一个大单位研究红外。1972年起,生产红外探测器才成为主要业务。1976年,开办了一家专门搞红外的工厂。用于红外的年营业额占26％左右。最初生产过许多导弹制导系统用的硫化铅光导探测器。之后,制备了各种材料的探测器,如锗掺汞(性能虽好,但太贵)、硫化砷(制备时不安全)和锑化铟。目前采用的是非常坚固而性能很高的啼镉汞探测器(8～14微米)。RMP公司最近投放市场一系列主要供民用的新的11微米碲镉汞探测器。Thomson-CSF公司为卫
Infrared detectors A few French companies, especially the SAT (France Telecom Co., Ltd.), have a high level of infrared detectors. In 1970, SAT had only one large unit studying infrared. Since 1972, the production of infrared detectors has become the main business. In 1976, a factory specialized in infrared was opened. The annual turnover for infrared accounts for about 26%. Initially produced a number of missile guidance systems used lead sulfide photoconductive detectors. After that, detectors of various materials, such as germanium doped with mercury (good but too expensive), arsenic sulfide (unsafe to prepare), and indium antimonide were prepared. Cadmium mercury detectors (8 to 14 microns) are currently very robust and high performance. RMP recently launched a family of new 11-micron HgCdTe detectors for civilian use.
