Paper Abstract

In pulsed blue-green laser radar applications, the signal return amplitude can have a dynamic range of 9 orders of magnitude in 200 ns. Signal compression is required to match this range to the input capabilities of the digitizing or processing devices, typically 2 or 3 orders of magnitude. The compression of the dynamic range of the signal by photomultiplier space charge control (P5CC) results in an adjustable compression range, variable gain, bandwidth in excess of 100 MHz, and extended input dynamic range, with no loss of photomultiplier sensitivity (i.e. photon counting operations are still achievable).
