Device for detection with time delay and phase integration

摘要

The device for detection with time delay and phase integration comprises detectors arranged in rows and columns. Capacitors for storing electric charges are associated with each detector. Any one point of the image is received sequentially by the detectors of a given row and each column of detectors is addressed sequentially by a shift register. The data stored by the detectors of a given row are received sequentially on a common lead by a charge-coupled device associated with each row. The function of this device is to delay the data delivered by the detectors of the same row in order to add these data in synchronism. The charge-coupled devices are located externally with respect to the rows of detectors. Their outputs are connected as feedback to their inputs in order to re-inject into the device the information previously received from a detector in phase with the information received from the following detector of the same row.
