Abstract
The theory and applications of optical fiber chemical sensors are discussed. Several transduction mechanisms for measuring the quantity of chemical species such as carbon monoxide, hydrogen sulfide, or toxic substances in the air or water are explained. A new frequency domain method which utilizes (chemo-optic) variable index material optical fiber couplers is also proposed for the application in distributed sensing.
