  4. 4. All-fibre optical sensor system for chemical sensing based on fibre Bragg grating technology

    Detta är en avhandling från Fysiska institutionen

    Författare :Adel Asseh; KTH.; [1997]
    Nyckelord :;

    Sammanfattning : This thesis deals with the realization of an all-fibresensor system for chemical sensing through the evanescentfield, based on fibre Bragg grating technology. The advantagesof all-fibre systems are most apparent for the potential userof the system. These systems are of small size, have highmobility, and require no precision alignment. LÄS MER
