An Infrared Micro Scanner Measurement and Calibration Method Based on Image Processing

In infrared imaging systems, in which the core is an infrared focal plane array, a microscanner can enhance the spatial resolution of the entire system. To test microscanners, this study developed a measurement and calibration method based on image processing and built a system to measure and calibrate microscanners. Using a microscanner as a test subject, the test results indicate that the proposed method has a significant effect on the measurement accuracy, repetition accuracy, and uncertainty. The method can provide technical support for the design and manufacture of microscanners.
