40case <strong>of</strong> <strong>microbolometer</strong> <strong>array</strong>, it will be most likely to be activated as a cooler due to heatbuildup inside the <strong>array</strong> packaging during the process <strong>of</strong> imaging.Figure 4.4 Inside <strong>of</strong> a UFPA packaging [81As shown in Figure 4.4, a thermoelectric cooler is placed underneath the<strong>microbolometer</strong> UFPA within the packaging. It will pump the heat from the inside <strong>of</strong> thepackage to the outside through back side conduction, which is attached to a heat sink.
