红外辐射的发现可追溯到十九世纪中叶,但直到二次大战结束,红外技术仍然只是刚刚脱离学院式的研究。在40年代中期,只有少数公司从事其发展,进行工业和军事应用的科学家和工程师不到100人。今天,红外科学受到人们广泛和积极的支持,红外装备的应用主要受到这一领域内人们设想能力和技术水平的限制。 The discovery of infrared radiation dates back to the mid-nineteenth century, but it was not until the end of World War II that infrared technology was still just emerging from academic research. In the mid-1940s fewer than 100 scientists and engineers were employed in their development and industrial and military applications in a small number of companies. Today, infrared science is widely and positively supported by people. The application of infrared equipment is mainly limited by the envisaged ability and technical level of people in this field.
