The responsivity of an infrared bolometer detector is deduced from electrical measurements, even for cases when the temperature sensor has electrical nonlinearities.Abstract:
An analytical method for determining the absorbed energy calibration of an IR bolometer from purely electrical measurements is presented. The technique is targeted at detectors with purely electrical nonlinearities. It is shown that the responsivity can be derived from the I-V plot if the limiting high-frequency impedance is measured. The electrical nonlinearity is then the difference between the impedance and the dc resistance. The model is used for designing a circuit for measuring the relative impedance parameters. The results are applicable to studies of IR sources and the detection of energy pulses with bolometers.read more

The General Theory of Bolometer Performance
TL;DR: In this article, a general phenomenological theory of the static and dynamic behavior of bolometers is presented, which assumes as given the fundamental relations between the temperature and resistance of the bolometer, and the past history of the power dissipated within it.

Bolometers: ultimate sensitivity, optimization, and amplifier coupling.
TL;DR: A resonating capacitor is shown to improve the coupling to an amplifier, so that the amplifier need not limit performance even for very low temperature bolometers.

Non-ohmic conductivity of barely localized electrons in three dimensions
TL;DR: In this article, the authors observed a rapid temperature variation and an electric field dependence of the d.c. conductivity in a carefully characterized sample of P doped Si, combined with measurements of Raman scattering, far-infrared absorption and magnetic susceptibility, indicate a large characteristic electronic length (10^4 times the donor Bohr radius) at a donor concentration just below the critical density of the metal-insulator transition.
