A Laser Radar for precise 2D-and 3D-Object Imaging

A high resolution laser radar useful for object scanning, profile measurements and level control has been set up. The distance measurement uncertainty is less than 300¿m, the spot size, which defines the lateral resolution, is less than 1mm. Powerful picosecond laser pulses are used to scan also surfaces with low reflectance. Although the pulse repetition frequency (PRF) is relatively high (40kHz), eye-safety laser condition class 1 is fulfilled. Scanned objects can be drawn as a 3D-wireframe (useful for 3D-modelization) and as a 2D-contour plot.
