Optical 3D imaging and visualization of concealed objects

Multiresolution greedy algorithm dedicated to reflective tomography

“…The idea is to apply a tomographic algorithm on reflective projections [13,11,6,2]: a filtered backprojection. It offers several ways of representing the scene [7,3,5,9] in three-dimensional optical imaging. The most intense values of the reconstruction are located near the original surfaces, up to artifacts.…”

An Exact Radon Formula for Lambertian Tomography

“…Over the past decades, there has been a considerable interest in developing new imaging modalities based on scattering of light and extensions of the Radon transform, such as Compton scattering tomography [17,20], Bragg scattering tomography [21], or reflective tomography [2,3,8,11,12,19]. This paper deals with reflective tomography in visible to near-infrared optics.…”
