Physical Layout of Semiconductor Bolometer<br />
Detection of Light: <strong>Lecture</strong> <strong>10</strong><br />
A chip of doped silicon or germanium acts<br />
BOTH as bolometer detector<br />
AND thermometer<br />
High input impedance amplifier measures the voltage<br />
Voltage depends on resistance<br />
Resistance depends on temperature
