Abstract

In optical remote sensing systems especially the imaging systems the quality of the scanner is the key element for obtaining high quality 2-D image of the target. There must be a detection device to verify the scanning performance of the optical scanner. In this paper such a detection device was developed. It consists of large area CCD camera, specific optical lens, electronics shutter, computer control element and scanning performance analysis software. The core technologies in developing the device are to design the specific optical lens, eliminate the delaying trail in the detecting image and recognize and analyze the spot matrix in the detecting image. The detection field of view can be wider than 10^o×10^o and resolution better than 0.1mrad. This device can not only perform real time detection on line, displaying dynamic values of all the detecting parameters, but also perform off line, displaying values of various detecting parameters for a given image taken at anytime. To consider the objectivity and creditability of the detecting result, there is an adjusting program to ensure the collimation between the detection device and the given optical scanner.
