Abstract

The measurement range of ceilometer depends both on its optical system characteristics and on the properties of its electronic scheme, including the detector. The optical system of the ceilometer is required to have the lowest possible number of elements and small size. Thus, it appears to be promising to optimize the device characteristics by selecting the detector and the laser characteristics. Signals received in the scheme were compared for two types of photodetector: the first option was the conventional APD detector, and the second one was the HD-SiPM detector. The objective was to study the analog signals for these detectors in a ceilometer that registers the signal backscattered by aerosol. The shape and the features of the signal and the shape of the wavefront registered by these two photodetectors in the scheme are discussed.
