Thermomechancial Characterization In A Radiant Energy Imager Using Null Switching
Keywords

Abstract
Thermomechanical noise for a MEMs-based infrared detector using null switching (US patent 7977635) depends on vibrational amplitude, since IR radiation is transduced to a change in the duty cycle of a repetitively closing switch. Equipartition theorem determines the maximum rms vibrational amplitude for the fabricated cantilever switch at its natural frequency. This determines the timing uncertainty, NEP, and NETD. We estimate NETD to fall in the range 0.13 - 1.5 K for a device with ~20 μm pitch. © 2014 SPIE.
