Scientific paper

Noise measurements in the frequency regions 5-200 Hz and .52 to 8.3 millihertz have been performed in the wavelength region between 300 and 3000 microns from the high altitude observatory of Testa Grigia, Italy (3.500 m). In the high frequency region, a specially designed Ge bolometer operating in background-limited-infrared-photoconductor conditions matched to a 1.5-m telescope has been used, while at low frequency a radiometer designed for atmospheric transmittance measurements was employed. In both regions, no excess noise with respect to the photon noise relative to 300-K blackbody has been detected.
