Uncooled Infrared Microbolometer Arrays and their Characterisation Techniques

Recently, a lot of attention has been paid to infrared imaging using uncooled microbolometer detectors, primarily because of their low cost, and wide military and civilian applications. This paper reviews the basic principles of these detectors and some of the important works done internationally in this field. This paper presents some of the research work on titanium microbolometer carried out at Solid State Physics Laboratory, Delhi.
