Optical system, terahertz emission microscope, and method of manufacturing a device |
摘要 |
There is provided an optical system, including: an extracting section, the refractive index of the extracting section being approximately the same as the refractive index of an observed object, the extracting section being optically coupled with the observed object to thereby extract a terahertz electromagnetic wave generated from the observed object; and an ellipsoidal reflector surface having a first focal point and a second focal point, the observed object being to be arranged on the first focal point, a photoconductive device being on the second focal point, the photoconductive device being configured to detect the terahertz electromagnetic wave extracted by the extracting section, the ellipsoidal reflector surface guiding the extracted terahertz electromagnetic wave to the photoconductive device. |
