Abstract
The results of study of the developed IR system based on the Fabry–Perot microresonator, functioning on the basis of the thermal-optical effect, are presented for its possible application in thermal imaging technology. The tuning factor of the Fabry–Perot microresonator calculated from the experimental data was kT = 0.44 nm/°С. An array of Fabry–Perot microresonators with pixel resonators in the form of 8 × 8 µm2 squares with a 2 µm gap in the amount of 640 × 480 pieces was made. It is shown that the characteristics of the developed thermal imaging system are not inferior to thermal imaging systems of a comparable class.
