For the former, it is time-efficient which should be attributed to the employment of FFT algorithms.
WebbTerahertz (THz) computed tomography is an emerging nondestructive and non-ionizing imaging method. Most THz reconstruction methods rely on the Radon transform, originating from x-ray imaging, in which x rays propagate in straight lines. However, a THz beam has a finite width, and ignoring its shape results in blurred reconstructed images. … WebbA novel shape reconstruction method based on zero-curl gradient field estimation is presented in this paper. Zero-curl field estimation makes the most of curl information to …
Webb17 jan. 2005 · We use a simulated wavefront to compare the two reconstruction methods. The slope of all subapertures is calculated by integrating the gradient of the wavefront function over one microlens (in our case 64 × 64 pixels). The slope values are saved and used for all reconstruction calculations.
