We have observed the photon noise by measuring a response to the black body 350 GHz
radiation and noise of the cold-electron bolometers (CEBs). The experimental results have
been fit to the theoretical model of CEBs with two heat-balance equations. The measured
noise has been decomposed into several terms with the help of theory. It is demonstrated
that the photon noise exceeds any other noise components, which allows us to conclude
that the bolometers measure the photon noise. Moreover, a peculiar shape of the noise …
