Abstract

The scanning imaging system has low frame rate due to the long period of point-by-point scanning especially for the large-sized object, while the array imaging system with relatively high frame rate is employed to image for small-sized objects due to the limit of the detector size. In this paper, a novel imaging system applying the scanning imaging setup and a 124×124 array detector is constructed and the software based on Visual C++ is designed to control the scanning process, collect image data, display the imaging result and the image mosaic process, and store the complete image. Utilizing the 2.52-THz laser generated by the SIFIR-50FPL as the imaging light source, preliminary imaging experiments are done. The imaging results are basically clear and image stitching effect is comparatively satisfying. Comparing with the point-by-point scanning imaging system, the frame rate is improved. Comparing with the array imaging, the setup is able to image for large objects utilizing the scanning system.
