Abstract :
A new composite bolometer for Fourier transform spectroscopy was designed for the range from 0.1 THz to 3 THz aiming to achieve a higher dynamic range at similar detectivity as commercially available silicon composite bolometers. It is based on a thin film metal mesh absorber, a superconducting thermistor and SiN membrane technology.
