Photodetector module for recording lidar signals

摘要

The useful model relates to the field of technologies for remote laser monitoring of the optical and physical parameters of the atmosphere, including the parameters of aerosol and cloud fields of the atmosphere, monitoring the distribution of smoke plumes of forest fires and emissions from industrial enterprises, etc., depending on the optical and meteorological state of the atmosphere in A sensing session requires a prompt change in the signal amplification factor, the avalanche photodiode cooling temperature and the magnitude of its high-voltage voltage. A useful model eliminates this drawback due to the fact that the digital control module is based on a programmable microcontroller. This increases the speed of the module and makes it possible to create algorithms with flexible changes in the measurement logic, i.e. promptly change the signal amplification factor, the temperature of the avalanche photodiode and the magnitude of its high-voltage voltage according to the laid down algorithm and taking into account the parameters of the recorded signals.
