Lidar receivers without overlap of the photomultiplier's single pulses

Lidar receivers of linear performance without overlap of the single pulses are analyzed. The statistics of output signals are investigated by using a model of the photoreceiving system that is based on the conversion of secondary electron trains into single-frequency decayed oscillations. I show that the lidar profile can be separated into nonuniform and uniform parts and a background and sampled by low-speed analog-to-digital converters (12-16 bits/0.01-100 kHz) to provide high amplitude and temporal resolution. The nonstationary background is reduced without chopping to the square root of its intensity. The use of the lidar receivers is discussed.
