Abstract
A fiber optic sensor module, for use with an optical sensor of the type that senses a selected parameter and modifies a predetermined characteristic of a received optical signal in corresponding relation to changes in the sensed parameter and retransmits the modified signal, includes an optical signal source having a selected predetermined characteristic and optical connections for providing the optical signal to the optical sensor. Signals retransmitted from the optical sensor are received and are differentiated from the transmitted signal so that the modified signal may be detected to provide an electrical output corresponding to the extent the predetermined characteristic of the optical signal is modified. The module is connected to the optical sensor using an optical fiber so that the sensor may be remotely located from the module and easily disconnected therefrom so that the module may be reused while the sensor may be disposable.
