"Nettetpushbroom camera is a linear sensor that takes 1-D images at several time instants. The sensor sweeps out a region of space; stitching together all 1-D images gives a complete 2-D image of the observed scene. This acquisition process is summarised in ﬁgure1(a). As a result of this process, pushbroom sensors have the advantage of providing higher " - Linear pushbroom cameras
