Characterization of noise in uncooled IR bolometer arrays

An extensive noise analysis on an Uncooled IR camera was performed. Direct noise measurements on individual bolometers were verified, and several new experiments to reduce their noise were performed. The data shows that 1/f noise in bolometers can be substantially reduced by changing physical characteristics of the device. Noise tests on the overall system revealed the major sources of noise present in the system. A simple model was developed to provide a framework for discussing the system noise results. The major noise components were all identified and characterized. Thesis Supervisor: Clifton G. Fonstad Title: Professor of Electrical Engineering and Computer Science
