Design of Infrared MicroscopeThis thesis introduces a way to arrange the setup of infrared microscope so that it is theoretically feasible to realize the experimental infrared microscope. The most challenging problem mainly resolved in this paper is how to increase the really low SNR from {10}^{-8} to a measurable value. The process includes introducing an Optical Amplifier, such as Quantum Cascade Laser Amplifier, and applying sensitive detector, such as HgCdTe PD/APD with lock-in Amplifier. Finally, we also discuss about a way to arrange the infrared optical system and introduce a sample design of a high NA infrared objective (NA=3.7).
