▎ 摘　　要

NOVELTY - The bolometer has a graphene sheet (120) which comprises a pair of contacts (330) and is configured to receive electromagnetic waves and to possess a temperature, when electromagnetic power in the received electromagnetic waves is absorbed by the graphene sheet, corresponding to the amount of electromagnetic power absorbed by the graphene sheet. The thermal noise is generated at the pair of contacts at a level corresponding to the temperature. A Fabry-Perot resonator comprises two mirrors and the graphene sheet is provided between the two mirrors. A circuit is connected to the pair of contacts and is configured to measure the thermal noise level. The first layer of hexagonal boron nitride is immediately adjacent to a first surface of the graphene sheet, and a second layer of hexagonal boron nitride is immediately adjacent to a second surface of the graphene sheet. USE - Bolometer used in imaging system (claimed) such as sensitive imaging system and analogous imaging system e.g. microwave reflector and, in communication system. ADVANTAGE - The reflector at the front end of the waveguide is partially reflective, to allow the infrared light to enter the resonator, and the reflector at the other end of the waveguide is highly reflective, to avoid allowing light to escape from the back end of the waveguide. The overlapping of the current antinode and the graphene sheet results in critical coupling of the received electromagnetic radiation to the bolometer to provide enhanced detection efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the bolometer sensor assembly. Waveguide (110) Graphene sheet (120) Bolometer sensor assembly (124) Substrate (310) Contacts (330)
