Abstract :
Methods of mathematical modeling are always used while studying physical processes. Mathematical modeling has appeared to be very useful in the development of measuring devices. Computers are also used for analysis of signals in these cases. This paper proves that mathematical modeling and computer analysis of signals allows one to measure the fast changes of optical radiation power of a thermal receiver, which has a large time constant. The receiver of radiation is a graphite plate with a width of 5 mm. The thermocouples are located on the back surface of the plate. The time constant of the receiver was about 300 sec
