Abstract

A method for operating a focal plane array in a Time Delay Integration (TDI) mode, the method including: shifting a number of rows during TDI integration, wherein the number of rows shifted is less than a total number of rows of the focal plane array; and reading out a number of rows equal to the total number of rows of the focal plane array minus the number of rows shifted, leaving behind the partially-integrated rows.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 61 / 713,474, filed October 12, 2012, the contents of which are hereby incorporated by reference. technical field [0003] The invention relates to the field of image scanning, in particular to time delay and integration (TDI) scanning using a CCD imager. Background technique [0004] Interline CCD imagers can be operated in TDI mode, for example, as defined in U.S. Patent 4,922,337, as in conventional TDI cameras to expose moving objects in non-stop motion, while also performing conventional video Live or take long exposures of stationary objects that are not practical with traditional TDI cameras. So, for example, it is possible to scan a large area at high speed by continuing to move, and then return to a very small, high-magnification, stationary region of interest with the same camera and equipment. [0005] When the inter-row CCD ope...
