The use of signal-generating image tubes (image orthicons) provides a number of features which are important for applications in tracking and surveillance sensor systems. The most significant features are: high quantum efficiency and internal noise-free signal amplification; scanning in the image orthicon of the transfer charge pattern generated by the optical image, which provides a means for time-sequencing of the spatial intensity information contained in the image; electronic image enhancement; digital image transfer and noise elimi-nation; real-time photometric and spectro-radiometric information retrieval; digital pointing-error information for automatic-tracking feed-back loops. The quantity which describes the performance of sensor systems is the modulation transfer function; in image tube systems the transferred spatial modulation of intensity amplitudes can be easily obtained from the video display on an oscilloscope.
