| abstract | (57) 【Abstract】 PROBLEM TO BE SOLVED: To realize spectrum measurement without using a spectroscope, to realize real-time, high-speed, and high-sensitivity spectrum measurement in an infrared region, and to perform optical system measurement at extremely low temperatures. An object of the present invention is to provide a spectroscopic device having a simplified structure. A spectroscopic element (1) made of a semiconductor heterojunction, A superconducting magnet 2 for applying a magnetic field to the spectroscopic element 1 is cooled with liquid helium 3, and a measuring light 3 is incident on the spectroscopic element 1 to measure the conductivity of the spectroscopic element 1. An apparatus 7 for calculating the optical spectrum of the measurement light 3 from the change in the conductivity corresponding to the change in the magnetic field. |
