ABSTRACT
A detailed thermal simulation of the dual-band microbolometer was performed using CoventorWare. This chapter describes the design and modeling of a smart uncooled infrared detector with wavelength selectivity in the long-wavelength infrared (LWIR). It dicusses dualband microbolometer model is presented. The commercial and defense sectors would both benefit from uncooled dual-band cameras: highway safety, medical diagnostics and surgery, surveillance, law enforcement, and security. A schematic of the dual-band microbolometer along with the structural view and operational view. A microbolometer is a thermal sensor whose resistance changes with temperature, associated with the absorption of IR radiation. The actual temperature and unique signature of objects in the scene can be discriminated if spectral response of the uncooled microbolometer is changed before each exposure to IR power. The microbolometer performance was also calculated for narrower electrode arms and for shorter support arms. A dual-band microbolometer is designed based on semiconducting vanadium oxide infrared-sensitive material.
