By the special introduction of the performances, the features and the main application of infrared remote sensors and imaging spectrometer on the type of the airborne and the spaceborne, the paper discusses and evaluates the present developing situation of the infrared remote sensing technology. To prospect 90's, the infrared remote sensor of new development will have used in resouces investigation, enviroment monitoring, observation of atmosphere and meteorology and ocean, measuring of the earth radiation and observation of the astrochemical as well as military purposes. The paper also introduces the scientific frontier of tile future infrared remote sensing techniques and experimental plan for the shuttle and the space station. Author points out the systematic engineerings of infrared remote sensing application that our country may develope and its researching directions.
