Abstract

The multiplexing of fiber optic sensors has been a subject of considerable interest for a number of years. The majority of the techniques presented to date, however, have depended upon a division of the power input to the system among a number of sensors. In this paper, a technique is presented whereby all of the power input to the system is sequentially routed through each sensor in turn. This is done through the use of electrically passive photoactivated optical switches with known time constants. An analysis of the technique is carried out and incorporated into a computer model to predict system performance. A comparison of the technique with other multiplexing concepts is also made.
