Focal plane array testing is a specialized field of test engineering. Focal plane array (FPA) imaging devices are used in missile guidance sensors, infrared astronomy, manufacturing inspection, and thermal imaging. Focal plane array testing is the process of verifying and validating that these devices function correctly. Focal plane arrays are complex to develop, in some cases the fabrication process may have more than 150 steps, testing of these devices must ensure that each step has the desired result. The actual test methodology used for testing focal plane arrays differs depending on the type of device. However, the types of tests usually fall into one of the following categories: diagnostic, performance, statistical, system simulation, or end-to-end simulation.
