ABSTRACT
We have seen in the previous chapter the limitations of an optomechanical imaging system in generating high spatial resolution imagery from space platforms. The limitation primarily arises from the mode of imaging on an instantaneous geometric field of view (IGFOV) by IGFOV basis, thereby limiting the time to collect the radiation. The situation can be substantially improved if data are collected for an entire strip by imaging the complete swath at a time, since all the pixels of the strip get the integration time corresponding to the time taken by the satellite to move through one IGFOV. Such a mode of operation is possible due to the development of long array detectors.
