5radiation (LWIR) between 811m to 1211m, popularly used for room temperatureradiometric measurements, is the region where the emission of infrared radiation fromroom temperature objects is the highest. To detect this region with photon sensingdevices, expensive materials, such as HgCdTe, are used. On the other hand,microbolometer can be easily modified to observe 8ium to 121.1m infrared wavelengthrange by using filters and by adjusting detector material absorption range.With the reduction of cost, there are several applications that can benefit from it.For military application, there are applications such as weapon sights for individualsoldiers, crew-served weapon sights, sensors for missile seekers, and driver's aides forcombat support vehicles. For industrial and commercial application, there are suchapplications as electric and mechanical troubleshooting, surveillance camera for policeand INS, home and business security system, landing aids and traffic monitor for airportsand aircrafts, and IR goggles for firefighters [4].
