Paper Abstract

An ultrathin fiberscope that incorporates illumination and detection into a single channel is presented for broadband diffuse reflectance imaging. It consists of a 0.5 mm diameter imaging catheter (coherent fiber bundle cemented to a grin lens), illumination and collection optics, and a ccd camera. To obtain reasonable image contrast, surface scatter and the specular reflections at interfaces of differing refractive index must be reduced. In this paper, the prototype system is modeled end-to-end in a non-sequential ray tracing program with the aim of locating sources of residual backscatter and backreflections. Analysis of results from two test objects, text and tissue, are presented.
