ABSTRACT:
A wide band clock controlled delay line for reading-in short pulses at high peed and reading them out at low speed comprises in one embodiment an array of charge coupled photon detectors (CCPD's) and a CRT circuit for generating and scanning an electron beam across a short persistence phosphor face to thereby excite the phosphor to emit radiation with an intensity proportional to the electron current in the scanning electron beam. The scanning rate for the beam is sufficient to operate on short pulses from a wide band system. An input signal driver applies an input signal to the CRT circuit to control the intensity of the electron beam, and a lens collects and focuses the light emissions from these phosphors on to the array of CCPD's. A clock pulse generating circuit generates clock pulses at a much slower rate than the scanning electron beam steps from one CCPD to the next for stepping out the charge stored in the array into an adding circuit.
