TERAHERTZ WAVE DETECTION APPARATUS, CAMERA, IMAGING DEVICE, AND MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a terahertz wave detection apparatus which suppresses deterioration of detection sensitivity due to electrical noise.SOLUTION: A terahertz wave detection apparatus 100 comprises: an absorption unit 60 absorbing a terahertz wave to generate heat; and a conversion unit 30 converting heat generated by the absorption unit 60 into an electric signal. The absorption unit 60 includes: a dielectric layer 62; a plurality of metal structures 64 provided on one surface 62a of the dielectric layer 62 and arranged separated from each other at a cycle with a predetermined length; and a metal layer 36 provided on the other surface 62b of the dielectric layer 62. The cycle with a predetermined length of the metal structure 64 is smaller than the wavelength of the terahertz wave absorbed by the absorption unit 60.
