Abstract At the present time there are commercially available large un‐cooled micro‐bolometer arrays (as as 1024×768 pixels) for a variety of thermal imaging applications. Different thermo‐sensing materials have been employed thermo sensing elements Vanadium Oxide (VO x ), metals, and amorphous polycrystalline semiconductors. Those good characteristics but also some disadvantages. As consequence none contain optimum pixels with an material. This paper reviews development bolometer technology...
