(physics) A sensitive device for detecting and measuring the energy of electromagnetic radiation.

Conceptual schematic of a bolometer. Power, P, from an incident signal is absorbed and heats up a thermal mass with heat capacity, C, and temperature, T. The thermal mass is connected to a reservoir of constant temperature through a link with thermal conductance, G. The temperature increase is ΔT = P/G and is measured with a resistive thermometer, allowing the determination of P. The intrinsic thermal time constant is τ = C/G.
