Paper Abstract

Progress towards a distributed optical fiber fluorosensor for pH is reported. The operation of the sensor is based on the pH dependent quenching of fluorescein dye immobilized in the porous cladding of a PCS optical fiber which has been stripped and reclad in a sol-gel coating. The analyte distribution is recovered from the OTDR response of the system to a short excitation pulse.
