Paper Abstract

Systems enabling uncooled infrared arrays capable of imaging room temperature scenes employ thermal detection mechanisms such as the resistive bolometric, pyroelectric/field enhanced pyroelectric and thermoelectric. All such approaches are subject to the fundamental limits of temperature fluctuation noise and background fluctuation noise. The thermal isolation structure is the most important item in optimizing the pixel design. Although it is possible to attain the limits with mechanisms which do not require bias, such as the thermoelectric or pyroelectric, it is probably easier to do so with mechanisms which require bias, such as the resistive bolometric and the field enhanced pyroelectric.
