Abstract
A scanning focal plane sensor and method are described for image capturing of object space (or scenes). In one example, a focal plane sensor for a scanning imaging system is provided. The focal plane sensor for a scanning imaging system includes M×N Time Delay Integration (TDI) imaging Charge Coupled Device (CCD), where M is a number of TDI columns and N is a number of TDI stages per each column. A detector is connected to each TDI stage. The focal plane sensor includes an imaging controller configured to mechanize sampling the brightness value of each sensor pixel's initial footprint in object space and select a number of charge integrating TDI stages for substantially equalizing the inter sensor pixels' signal to noise ratios.
