In China , the techonology of spectral information , especially the IR spectral information are attractive in airborne remote sensing field. The main recent progresses of some typical airborne spectral remote sensing systems are introduced in this article .

The optical scanning technology in an airborne scanning laser ranging-imager sensor

The Airborne Scanning Laser Ranging-Imager Sensor (ASLRIS) is a new generation of remote sensing and mapping system to acquire 3D geosciences information which integrates the laser altimeter, IR imager, DGPS and inertial reference system, by which a digital elevation model and georeferenced image can be generated quickly and effectively without ground control point. The GPS solution of the critical positioning problem gives high accuracy potential. The high repetitive pulse lasers give clearly recordable return signals after diffusion and reflection on the ground. Precise kinematics positioning of the platform by DGPS and inertial attitude determination by IMU provide the accurate reference to an external coordinate. The passive scanning imager, which shares the telescope and the scanning mirror with the active laser ranger, provides the infrared image. A suitable optical scanning technology is important to satisfy the demand of high-speed scanning and high-resolution laser ground sampling with limited repetitive rate of laser. Two scanning optic-mechanisms are developed and applied in the ASLRIS in sequence.

Mineral exploration by use of infrared multispectral remote sensing in China

A new airborne infrared multispectral technology has been used for study of the gold and other mineral exploration in the North-Western Part of China during past few years.In this study the following steps were involved:the measurements and analysis of spectral character-istics, airborne remote sensing data acquisition and processing , extracting information on mineralized features and the assessment of techniques.
