Abstract
A TDI scanner including a dynamically programmable focal plane array including a two-dimensional array of detectors arranged in a plurality of columns and a plurality of rows, the array being divided into a plurality of banks separated from one another by gap regions, each bank including a plurality of sub-banks, and each sub-bank including at least one row of detectors, a ROIC coupled to the focal plane array and configured to combine in a TDI process outputs from detectors in each column of detectors in each sub-bank, and a controller configured to program the focal plane array to selectively and dynamically set characteristics of the focal plane array, the characteristics including a size and a location within the two-dimensional array of each of the plurality of sub-banks and the gap regions, the size corresponding to a number of rows of detectors included in the respective sub-bank or gap region.
