A [[microbolometer]] is a specific type of bolometer used as a detector in a [[thermal camera]]. It is a grid of [[vanadium(V) oxide|vanadium oxide]] or [[amorphous silicon]] heat sensors atop a corresponding grid of [[silicon]]. [[Infrared]] [[radiation]] from a specific range of [[wavelength]]s strikes the vanadium oxide or amorphous silicon, and changes its [[electrical resistance]]. This resistance change is measured and processed into temperatures which can be represented graphically. The microbolometer grid is commonly found in three sizes, a 640×480 array, a 320×240 array (384×288 amorphous silicon) or less expensive 160×120 array. 640x512 VOx arrays are commonly used in static security camera applications with low shock resistance requirements. Different arrays provide the same resolution with larger array providing a wider [[field of view]].{{Citation needed|date=October 2014}} Larger, 1024×768 arrays were announced in 2008.
