Abstract

The effects of the thermal link on the dynamic behavior of bolometric detectors are discussed. A simple unidimensional model is used to describe the heat diffusion in the link between the sensor and the bath, and the exact general solution is given for the coupled system. Calculations of the dynamic behavior in the time and frequency domains are shown for specific heat sources. A useful approximated formula for the effective heat capacity of the detector is given.
