Abstract
The Uncooled Focus Plane Array (UFPA) infrared detector is widely used in military and civil fields. With the features of small size and not being cooled, the Uncooled Infrared Focal Plane Array (UIRFPA) has become the focus in the current infrared thermal imaging research. A data acquisition system has been designed and implemented for measurement of the UIRFPA. The system includes driver module, acquisition module and signal processing module. The acquisition module based on virtual instrument can achieve high-speed, stable and accurate data acquisition. Meanwhile, combined with visual C+ + (VC) platform, the system realizes data acquisition and real time imaging. Through testing a 240×320 FPA using the test system, the superior performance of the device has been performed. In addition, the imaging effect has been enhanced by eliminating the bad pixels and proofreading the non-uniformity. A new test system for the test of UIRFPA and the exploration of the real-time correction imaging system is presented.
