description: This work is devoted to the modernization of the photodetector module of an optical disdrometer.
Tasks that were solved during the research:
1. Design development of a multi-element photodetector for an optical disdrometer with the aim of:
- detecting measurement errors of the speed, size and propagation speed of the rain stream;
- increase in measurement accuracy and data flow rate at low rainfall density;
- dynamic range expansion of the measured droplet sizes up to 200 microns and speeds up to 20 m / s;
2. Simplify and repair the design of the device for the counter of optical elements values (lenses and alignment devices) of the photodetector module;
3. Finalization of software for multichannel reception and processing of information.
The work was carried out in the laboratory Â«Optical methods for the diagnosis of polydisperse systemsÂ» ÐÐÐ¤Ð¨ ÐÐ¤ÐÐÐ¢.
A model of a multi-element photodetector has been created and experimental studies have been carried out to verify the operability of the models. The technical requirements for the structural elements of the photodetector and the electron - optical path are developed. A batch of multi-element silicon photodetectors based on industrial technologies was manufactured at the enterprise Â«ÐÐ­Ð ÐÂ» LLC . Thermal tests of photodetectors have been carried out. The technique has been improved and a software program has been implemented in the conditions of multichannel reception and processing of photodetector signals. The concept of a photodetector module has been formed.
