Paper Abstract

We present a thermal property estimation method required for a bolometer design and demonstrate the utilization of a presented method to the scaled μ-bolometers. The estimated thermal properties of 25μm pitch VOx bolometers with our presented method shows K=1.33x10-8 W/K, H=1.36x10-10 J/K, τth=10.2 ms for an active bolometer and K=1.64x10-6 W/K, H=1.82x10-10 J/K, τth=111 μs for a reference bolometer. These estimated thermal properties have a good agreement with the previous reports and with results from the FEM analyses carried on the same bolometer designs. The presented method is useful to estimate thermal properties of a scaled bolometer and to estimate thermal properties of a specific design.
