Abstract

In this thesis the characterization of a cryogenic infrared bolometer (Infrared Laboratories model, #3538) used by SRON - Netherlands Institute For Space Research, is presented. Several distinct setups were used to obtain important parameters of the bolometer, such as the responsivity, noise-equivalent-power, electronic 1/f noise, roll-off frequency and frequency response. We have found that the 1/f noise is present up to a frequency of ~5 Hz, an electronic roll-off frequency of 3 kHz, the detector's 3 dB roll-off frequency at ~600Hz and a responsivity of 2.22 · 10^5 +/- 1.4 · 10^4 V/W, which is in good agreement with the expected value given by the bolometer's manual. Furthermore we have analyzed the use of this bolometer in a Fourier transform spectrometer. Based on calculations regarding solid angle Ω, we indicate that the signal level in a Fourier transform spectrometer can be improved by a factor of ~380, if proper optics are used.
