24 August 1988 System Design Considerations Of CCD Based Line Imagers
Author Affiliations +
The application of CCD imagers for airborne cameras require a long focal plane (>12000 pixels), high light gathering capability, high MTF, low noise and low non-uniformity between elements. Optical butting of focal planes using the "beam sharer" technique enable the manufacture of a line imager with a light gathering capability which is at least twice the light gathering capability of similar line imagers that utilize the classical "beam splitting" technique. Some problems regarding the evaluation of such line imagers are discussed: - Diffraction effects that influence the image quality at the butting zone. - CTF and MTF measurements techniques including problems of interpretation when square-wave targets are used.
