Abstract
Because of long integral time and simple structure, pushbroom hyperspectal imager was paid more attentions in remote sensing field. But its field of view (FOV) is affected by the sensor so that pushbroom hyperspectral imager's work efficiency is not high. This paper describes a simple mention to enlarge FOV specially the way to mosaic two imagers. An imager with 42° FOV mosaic two imagers with 22° is introduced including the electronic system's designs and realizations. The design was introduced distribute network to solve the critical problems such as storage of huge data, the synchronization and mosaic of two sensors. The wide FOV pushbroom hyperspectral imager has a 42° FOV, 1304 spatial pixels and 124 spectral pixels. The imager has a bandwidth ranging from 400~900nm. It has been applied in the digital city plan of shanghai for water inspection and target classification.
