Paper Abstract

Owing to their low losses in the 2-12 micrometers region, the Te- As-Se glass fibers are used for infrared light transportation as well as sensing element based on evanescent wave absorption mechanism. The efficiency of the system is improved by tapering the fiber diameter in the sensing zone. With this kind of sensor, infrared spectra of biological tissue have been obtained. Spectra of mouse liver have been especially recorded in order to detect spectral differences between the healthy and the tumoral states of mouse liver.
