  • Signal sensing and measuring in fibre optic systems with light pulse width detecting
    Patent number: 5138152
    Abstract: In a fibre optic sensor control system using an optical fibre (14) responsive to an applied external pressure P and through which a series of pulses are transmitted, a detector (20, 22) is responsive to the pulse-width of the received pulses rather than merely their amplitude. This results in less susceptibility to interference and also makes the system less sensitive to changes in the transfer characteristics of the electro-optical convertor (12) and/or of the opto-electrical convertor (20) and/or the maximum transmittance of the optical fibre.
