Abstract:

Optical tomography provides visual images of the interior of objects. There are various methods depending on how the material behaves under scattering. If scattering is weak, one approach extracts the scattering amplitudes from the inputed projected images and estimates a cross-sectional image from images without scattering. Conversely, if the scattering is strong, an approach is to use the scattering amplitude to estimate the cross-sectional image. In this situation, light paths are scattered and a large field of view is required to observe all of the scattered light from which to construct the image. In this paper, we propose a method based on computed tomography which employs wrap-around viewing. We implement a projector-camera system that can send and then with an ellipsoidal mirror receive light scattered from an object from all fields of view. In addition, this system with mirror does not need any mechanical motion to capture scattered light during scanning.
