Bolometer Thermal Time constant<br />
The total power absorbed by the detector is:<br />
T1(t) = PT<br />
G<br />
Detection of Light: <strong>Lecture</strong> <strong>10</strong><br />
PT (t) =P0 + PV (t) =GT1 + C dT1<br />
dt<br />
Now we turn on a signal so that: t0<br />
The time constant is T = C/G<br />
For t>>⇥T the temperature T1 ⇠ (P0 + P1)<br />
...so if you measure the temperature then you can know the power
