(FR) SYSTÈMES DE SONDE OPTIQUE DE TOMOGRAPHIE PAR COHÉRENCE OPTIQUE ET PROCÉDÉS DE RÉDUCTION DES ARTÉFACTS
Abstract
(EN)
A system for reducing artifacts produced in images using an optica! probe system is provided. The artifacts are reduced by reducing power of secondary beam paths produced by non-Fresnel reflections by at ieast one of absorption, scattering and rejection of the secondary beam paths.
(FR)
L'invention concerne un système pour réduire les artéfacts produits dans des images au moyen d'un système de sonde optique. Les artéfacts sont réduits en réduisant la puissance des trajectoires de faisceau secondaire produit par des réflexions non-Fresnel au moyen d'absorption, de diffusion et/ou de rejet des trajectoires de faisceau secondaire.
