Implementation of the time delay and integration mode in a scanning 576 × 6 focal-plane array of the long-wave infrared range

Аннотация

The results of the development of a focal-plane array (FPA) of the 576 × 6 format with the time delay and integration (TDI) mode are presented. The comparative analysis of different variants of implementation of the TDI mode in ROIC is conducted. The expedience of the upgrade of existing scanning photodetectors of the 288 × 4 format on the basis of the developed 576 × 6 FPA is justified. The result of this upgrade will be simplification of the optical–mechanical scanning unit and improvement of the quality of thermal image.
