Abstract

In master's qualification work mathematical models of pyroelectric crystal and transistor structures have been developed and studied, which allow to take into account the change of active and reactive components of full resistance from the action of power of optical radiation, and also allow to investigate its influence on active and reactive components of full resistance. The analysis of errors of the device and calculation of the economin-infrared effect from its introduction is carried out. Analytical expressions for calculating the total impedance of the frequency converter, which, unlike the existing ones, allow to determine the dependence of the active and reactive component of the total impedance on the action of the power of optical radiation. The developed optical radiation power measuring devices have optimal metrological characteristics (sensitivity 11.2 kHz / mW, total error of 0.18%), are compatible with digital information processing systems and can be manufactured using standard group integrated technology. All simulated circuits provide high sensitivity from 8.5 to 11.2 kHz / mW. Calculations on the efficiency of the device showed that its introduction into production is cost effective. Since the Current is <3… 5 years, it is advisable to finance this scientific development of a radiometer to determine optical power. When introduced into production, the manufacturer will profit. Analyzing the market we can count on a significant demand for our product. Confirmation of this is the technical parameters of this device, which are better than the parameters of the analogue. In the section OP covers such issues as safety in emergency situations, such as technical solutions for occupational hygiene and industrial sanitation, determination of laser power at a given safe distance, technical solutions for industrial and fire safety in carrying out the development of a radiometric device for determining optical power, safety in emergency situations.
