Abstract
Thermal time constant is an important parameter describing temporal behavior of bolometers as well as resistive layers used in these detectors. Measurement of the thermal time constant can yield valuable data for research and quality control. However, due to the influence of 1/f noise, this measurement is difficult to conduct, especially when the thermal time constant is longer than a second. Two setups, capable of performing such measurement in the range from milliseconds to a few seconds, were developed and are presented in the paper. Using these setups, thermal time constant of bolometers and resistive layers made from non-stoichiometric lanthanum-strontium-iron oxides (LSFO) in LTCC technology was measured. Results presented in the paper show that the setups can measure thermal time constant up to several seconds. Directions of further research are discussed.
