Paper Abstract

We present the 3D-imaging of a target using range gated laser systems operating at 1.5 μm. Two different illumination techniques were investigated: 1) a conventional illumination technique consisting of a Raman-shifted Nd:YAG laser with a fixed wavelength, and 2) a technique which makes use of a wavelength-tunable illumination source consisting of a Nd:YAG-pumped OPO. We compare the influence of each illumination technique on target induced speckle effects and the resulting range resolution. Image samples were taken at ranges of up to 2.5 km.
