Abstract
A wideband photorecording technique has been developed which will coherently record signals of 1 GHz bandwidth. Strobe illumination of the travelling acoustic wave pattern inside a wideband acousto-optic Bragg cell with sub-nanosecond laser pulses allows recording of the signal waveform by imaging the diffracted light onto photographic film. Coherent readout of a one millisecond record has demonstrated a signal to noise ratio of 25 dB (Speak/Navg).
