| Abstract: | In this paper, the theory of operation and the characteristics of modulation are described about pyroelectric detectors, which are used in infrared interferometric measurements. Several methods of modulation are compared and analysed. Finally, a method of phase-shifting modulation based on pyroelectric imaging is proposed and the effect of optimum modulation frequency on measurement is considered. Results of measurement are given. |
