-Single board computer to processes the digital signal from the camera and determines positioning to the object, and transmits the digital signal to the analog display - 3, where digital-to-analog converts the signal to the range of 0-5V. Using a board with an operational amplifier, we get a bipolar voltage - plus and minus 5 V, from which the boards with the motor driver for the galvanometer are powered - 4, from where the signal goes to galvanometers -7. The galvanometer uses mirrors to change the direction of the laser - 6. The system is powered by the power supply - 5. Cameras 2  determine the distance to the object. The camera detects mosquito and transmits data to the galvanometer, which sets the mirrors in the correct position, and then the laser turns on.
