Patent ID: 8022835

Claim:
A communication system for an optic type sensor comprising: (a) a transducer which receives an input light signal and returns an output light signal comprising two or more distinct components at least one of which changes predictably in relation to a pressure, force, or displacement acting upon a focusing reflective and or focusing transparent element of the transducer, wherein the characteristics of at least one component of the output light signal is affected in a different manner by the pressure, force or displacement acting on the transducer than the other component or components of the output light signal; (b) an input light signal; (c) a single strand optic fiber which conducts the input light signal from the light source into the transducer and returns a modified light signal along the same single strand optic fiber; (d) a light splitter located along the single strand optic fiber, between the light source and the transducer, which causes a portion of the returning output light signal to be transmitted into a separate communication channel; (e) a reader device which receives the returning output light signal spilt off by the light splitter and decodes it into a pressure, force or displacement reading; (f) a communication channel between the light splitter and the reader device.
