Abstract

This paper describes measurements to determine the performance and suitability of large area bolometers on thin dielectric membranes for use as wideband THz power meters. A Fourier Transform Spectrometer (FTS) was used to measure the transmission spectra of the bolometers from 0.6THz to 10THz. A linear array of bolometers was then fabricated and used to characterized the beam produces by a FIR laser at 802GHz and 2.54THz. The total power generated by the laser is determined by measuring the beam's profile and peak power density.
