Paper Abstract

Terahertz focal plane array imaging technology can realize real-time terahertz imaging with high frame rate. But for a relatively large-sized object imaging, the array scanning should collect a plurality of original image data due to the small-sized focal plane terahertz detector array. In this paper we demonstrate terahertz image preprocessing, image register and image blending in detail. In order to reduce the image noise and enhance the image contrast, we manifest a novel method to preprocess the image by incorporating of Butterworth band-elimination filter and high-frequency nonlinear enhancement methods. Meanwhile, the enhanced image is stitched using the sift algorithm. The experimental result present that the proposed method can accurately mosaic the terahertz grayscale image, which is beneficial to realize the scanning and stitching imaging of large-area objects by focal plane array terahertz detector.
