Prospects for the application of Fabry–Perot microresonators for thermal imaging equipment

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.
