ABSTRACT:
An optic sensor system comprising N optic sensors, each of the N sensors operating with received input light and providing output light having a characteristic corresponding to a sensed parameter; a number, less than N+2, of devices wherein each of the devices operates as a light source and as a light detector such that one device can be used to transmit interrogation light to two of the sensors, with two other of the devices being used to receive output light from the interrogated sensors; and optic waveguide means for transmitting light between the sensors and the devices.
