ABSTRACT:
The number of sensors that can be used by an SSA system including a single source can be increased by using a multi wavelength source to send different wavelength pulses to each of a plurality of different sensor array ladders, particularly Sagnac sensor array (SSA) ladders. More particularly, each broadband pulse from a broadband source is wavelength divided into a plurality of narrower pulses with each narrower pulse being used in a separate sensor array ladder.
