Claim:
1. An optical sensing system, comprising an interrogator system comprising a first optical sensor array configured to be interrogated by the first set of optical interrogation signals; a second optical sensor array configured to be interrogated by the second set of optical interrogation signals; a first optical receiver, for receiving the first set of optical interrogation signals; a second optical receiver for receiving the second set of optical interrogation signals a first optical connection for coupling the first set of optical interrogation signals from the first optical signal source to the first sensor array, and for coupling optical signals from the second sensor array to the second optical receiver; and a second optical connection for coupling the second set of optical interrogation signals from the second optical signal source to the second sensor array, and for coupling optical signals from the first sensor array to the first optical receiver.
