REMOTE SENSING METHODS AND SYSTEMS USING NONLINEAR LIGHT CONVERSION AND SENSE SIGNAL TRANSFORMATION |
摘要 |
A disclosed system (100) includes a light source (102) and a nonlinear converter (108A, 108B, 200, 220, 240) optically coupled to and remote from the light source. The nonlinear light converter converts a light pulse received from the light source to a broadened or spectrum-shifted light pulse. The system also includes a sensor (110A, 110B) in situ with the nonlinear light converter. The sensor performs a sense operation based on the broadened or spectrum-shifted light pulse and generates an electrical signal corresponding to the sense operation. The system also includes an electro-optical interface (112A, 112B) in situ with the sensor that transforms the electrical signal to an optical signal for conveyance to a signal collection interface A related method includes generating a light pulse and conveying the light pulse to a remote nonlinear light converter. The method also includes converting the light pulse to a broadened or spectrum-shifted light pulse. The method also includes performing a sense operation in the remote location using the broadened or spectrum-shifted light pulse and generating a corresponding electrical signal. The method also includes transforming the electrical signal to an optical signal for conveyance to a sense signal collection interface. |
