Abstract
An illustrative downhole sensing system and method employs an array of downhole sensors such as extrinsic Fabry-Perot interferometers, each of which provides a sequence of light pulses having spectra indicative of a measurand for that downhole sensor. An optical fiber conveys the sequences in a time-multiplexed fashion to a receiver having at least one gating element that passes only a selected one of the sequences and at least one spectrometer that receives the selected one of said sequences and responsively measures a light spectrum. Notably, the integration interval for the spectrometer measurement is substantially greater than the pulse period of each sequence, including multiple pulses within the measurement by the spectrometer.
