Abstract :
We have demonstrated that a logarithmic amplifier can dramatically improve the range of an existing lidar system. In addition, it provides the needed amplification for photomultiplier tubes and avalanche photo-diodes detectors without saturating the ADCs. We conclude that such an amplifier should be an essential component of an analog lidar system
