Multispectral Remote Sensing Systems | GEOG 480: Exploring …
The figure below (from Jensen, 2007, Remote Sensing of the Environment) shows six types of remote sensing systems, comparing and contrasting those using scanning mirrors, linear pushbroom arrays, linear whiskbroom areas, and frame area arrays. The digital frame area array is analogous to the single vertical aerial photograph.
