Abstract
Time delay and integration (TDI) imaging was first applied in the early 1970's to aerial photoreconnaissance as an electronic replacement for photographic film. Since that time, TDI has been applied elsewhere infrequently with bare printed circuit board inspection and document digitizing as the only well-known recent applications. Now, TDI has been effectively brought to bear on an ubiquitous problem, that of inspection of moving webs. Although other imaging techniques have been and are being used for web inspection, none shows the broad adaptability and ease of use of TDI-based imaging. Herein is a review of the TDI technique, a specific implementation of TDI in a unique web-imaging-compatible camera and a comparison of the TDI technique with other current technologies.
