We present the results of an experiment aimed to demonstrate the low-pass filter dependence of water backscattered power in an amplitude-modulated laser scanner for underwater 3D imaging. We also demonstrate that improvements in target imaging are obtained by allowing the device to operate in the stop-band region. A simple model is described to account for the physics underlying the effect and suggesting future experimental schemes based on demodulated detection techniques.
