Responsivity compared to photodetectors<br />

Photoconductor<br />

Sphotoconductor = ⇥qG<br />

hc<br />

Photodiode<br />

Sphotodiode = ⇥q<br />

hc<br />

Bolometer<br />

Sbolometer = 2I<br />

The bolometer responsivity is independent of the wavelength<br />

(assuming QE is independent of )<br />
