Footnotes
1) The following conditions are assumed: target is larger than the footprint of the laser beam, average ambient brightness, perpendicular angle of incidence, visibility 23km, ambiguity to be resolved by proper flight planning and multiple time around processing
2) Reflectivity p ≥ 20%, max. scan angle 60°, additional roll angle +/- 5°.
3) Standard deviation one sigma @ 250 m range under RIEGL test conditions
4) Accuracy is the degree of conformity of a measured quantity to its actual (true) value.
5) Precision, is also called reproducibility, or repeatability, is the degree to which further measurements show the same result.
6) User selectable.
7) 0.5 mrad corresponds to 50 cm increase of beam width per 1000 m distance
8) Practically limited only by the maximum data rate allowed for the Riegl Data Recorder
9) Minimum angle step width increasing linerly to 0.01° @ 80000 Hz laser pulse repetition rate
