DEFINITION
- A dark measurement is a normal measurement with sufficient time averaging, but with a fully covered telescope or with covered detectors.This signal shows all electronic stray pick-ups and signal distortions which do not stem from the atmospheric backscatter, but from the lidar system itself: e.g. laser flash-lamp pulse pick-ups, or system trigger pick-ups. All system parameters, like e.g. detector HV, must be set in the same way as for a normal measurement.
