Optical pressure measurements for biological applications.
01 January 1987
The use of optical methods in pressure transduction is a well established technique, and has been incorporated in many instruments designed for biomedical and industrial applications. Advantages of the technique include immunity to electromagnetic interference, electrical isolation of the transducer from the signal processing equipment and, in the case of single-fiber probes, small size. The attached material is a summary of a presentation to be given at the June, 1987, "International Workshop on Biosensors," sponsored by the Gesellschaft fur Biotechnologische Forschung in Braunschweig, W. Germany, and is intended for publication in the proceedings of the workshop. The presentation reviews progress in fiber optic pressure sensing, with a particular emphasis on fiber sensors suitable for biological applications, including illustrative examples of several different sensing methodologies.
