Endoscopic vision gives a projective image and thus no true scaling information can be directly deduced from it. In this article, an approach based on an interferometric setup, a low coherence laser source and a standard rigid endoscope is presented, and applied to hollow samples measurements. More generally, the use of the low coherence interferometric setup detailed here could be extended to any other endoscopy-related field of interest, e.g. gastroscopy, arthroscopy and other medical or industrial applications where tri-dimensional topology is required. The setup design with a multiple fibers illumination system is presented. Demonstration of the method ability to operate on biological samples is assessed through measurements on pig bronchi.[MVD]text::journal::journal article::research article
