热带有一种响尾蛇,在漆黑的夜间能捕获猎物,主要是在响尾蛇的头上有一种热敏器官.这种器官是生在鼻孔和眼睛之间的小窝,在每个小窝中不深的地方有一横隔膜,把小窝分成内外两部分.隔膜的厚度约0.025毫米,上面满布着神经末梢,能够感受动物体发出的红外辐射,响尾蛇就依靠它在暗处发现猎物.现代各种军事技术也应用了许多类似响尾蛇的对红外线敏感的仪器,用于观察、通信、导航、摄影等,特别是在各种火箭的控制方面发展得更为迅速,目前不仅在空-空导弹上,而且在防空导弹上、远程火箭上,都装着红外自动瞄准头.此外,在宇宙飞行导航系统上、人造卫星的跟踪仪器上,红外线技术也被广泛地采用着.
In the tropical there is a rattlesnake that captures prey in dark nighttime mainly on the rattlesnake’s head with a heat-sensitive organ that is a small socket born between the nostril and the eye and not deep in each socket There is a diaphragm, the nest is divided into two parts inside and outside.The diaphragm is about 0.025 mm thick, covered with nerve endings, can feel the infrared radiation emitted by animals, rattlesnake relies on it to find the prey in the dark.Modern military technology Also used are a number of infrared-like instruments similar to rattlesnake, used for observation, communication, navigation, photography, etc., and developed more rapidly, especially in the control of various types of rockets, not only on air-to-air missiles, Air defense missiles, long-range rockets, are equipped with infrared automatic aiming head.In addition, the space flight navigation system, the satellite tracking instrument, infrared technology is also widely used.
