instrument status check
true
Deviations of the near range signals from different parts of the telescope and the comparison of such deviations of different lidar channels and with theoretical ray-tracing simulations can reveal the distance of full overlap and possible reasons for the deviations from the ideal case. The test is based on the fact that the backscattered photons collected from the near range by different parts of the telescope of a lidar system must give the same range dependency of the signal, and if not, the range dependency of the whole signal is uncertain.
