AB - Space based multispectral remote sensing has gained considerable importance in providing information on earth resources in various disciplines. The LIS S -I and LIS S I I cameras of the Indian Remote Sensing Satellites IR S 1A/1 B have provided enormous data for remote sensing applications. From the point of view of data analysis and interpretation, the two important performance characteristics of multispectral cameras (sensors) are MT F and band to band registration. Band to band registration means that all the detectors corresponding to different spectral bands of a camera view the same area of the earth at a given instant of time.This paper describes the technique developed for Inter band alignment of multispectral CC D camera of the Indian Remote Sensing Satellite. Each multispectral camera (LISS) of IR S 1A/1 B consists of four spectral bands and each band assembly contains a refractive imaging lens filter assembly and a charge coupled linear array device of 2048 elements Each lens of E O module is assembled in such a way that the image format will be same for all the lenses and in the plane in which the format is matched, the MT F will also be maximum. The detectors of all the four bands are precisely oriented in the focal plane such that the different bands of the E O module view the same area at a given instant time. The alignment of CCD’s requires a positioning capability of less than a micron in a plane perpendicular to optical axis. It must be noted that the technique developed to accomplish this task does not make use of any micropostioners.
