Development of the High Efficient Scanning Mechanism Using in Optical Space Remote Sensor

In some remote sensing, such as meteorology and oceanography, wide swath scanning must be used. Owing to the limitation of the detector size, especially in infrared spectrum, the optical-mechanical scanning mode is necessary. Scanning efficiency is an important parameter of those scanners. The high scanning efficiency is one of the goals followed after by the designer of remote sensor. Two high efficient scanning systems are developed by authors. Those systems can have some advantages, such as simple and reliable.
