Programmable digital TDI EO/IR scanning focal plane array with multiple selectable TDI sub-banks

A time delay and integration (TDI) scanner comprising:

• 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 of detectors 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 read-out integrated circuit (ROIC) coupled to the focal plane array, the ROIC being configured to combine in a TDI process outputs from detectors in each column of detectors in each sub-bank to provide, for each sub-bank, a plurality of column output values;
• and
• a processor 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, the size corresponding to a number of rows of detectors included in the respective sub-bank, and the location corresponding to locations of the gap regions within the two-dimensional array,
• wherein detectors within the two-dimensional array corresponding to the gap regions are inactive in the TDI process and are shunted to ground.
