Shape from Focus Applied to Real- Time Terahertz Imaging

Thanks to significant advances in real-time terahertz imaging in term of resolution and image quality, the possibilities for 3D reconstruction are numerous. The Shape from Focus (SFF) algorithm is a post-processing tool used in optical microscopy to obtain the 3D object shape surface. We propose to apply this algorithm in active and real-time terahertz imaging. Thus, we report the investigation led on such an algorithm to manage 3D terahertz object reconstruction.
