Next-generation sensors for earth observation will utilize Multispectral Linear Array (MLA) technology wherein linear detector arrays will scan the earth in pushbroom fashion. Compared to earlier sensors utilizing cross-track scan mirrors, MLA instruments will permit a dramatic increase in detector dwell time, which can be exploited to improve spatial, spectral and radiometric resolution. Focal-plane technology development is key to these new sensors, because detector size and performance are critical factors that influence the entire sensor design.
