Luminescent optical fibers in sensing
1998The development of fibers doped with materials through which luminescence is generated has a long history, which follows upon the original proposal by Snitzer [1] in the early 1960s of the use of an optical fiber geometry for lasers and optical amplification, employing 300 μm core diameter neodymium doped fiber.

Bile sensing with optical fibers
SPIE Proceedings, 1999Bile determination is very useful to diagnose many gastric pathologies. Actually the measurement is performed with Bilitec 2000, an optical fibre sensor, based on the absorption by bilirubin. Nevertheless erroneous evaluations can occur due to different configurations which the bilirubin molecule can adopt.

Fiber-Optic Chemical Sensing With Infrared-Transmitting Optical Fiber
SPIE Proceedings, 1990Infrared transmitting heavy metal fluoride optical fiber has been used to separate a Fourier-transform infrared (FTIR) spectrometer from a remote measurement point. Several types of remote sensors have been developed for concentration measurements. Remote transmission cells connected to fiber cables have been used to measure near-infrared spectra of ...
