Abstract
Official abstract text for this publication.
A fiber-optic sensor array ( 100 ) comprises a line array of fiber-optic sensor packages (AX, BX, CX, DX, AY, BY, CY, DY, AZ, BZ, CZ, DZ) each having a package input/output (i/o) fiber and each being arranged to output a finite output pulse series of optical output pulses via the package i/o fiber in response to input thereto of one or more interrogating optical pulses. The array further comprises a fiber-optic bus ( 104,106, 108, 110 ) extending along the length of the line array, each package i/o fiber being optically coupled to the fiber-optic bus at a respective positions along the line array. The array allows interrogation at a higher frequency than is the case for a serial array of the same number of fiber-optic sensing packages.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fibre-optic sensor array comprising a line array of fibre-optic sensor packages each having a package input/output (i/o) fibre and each being arranged to output a finite output pulse series of optical output pulses via its package i/o fibre in response to input thereto of one or more interrogating optical pulses and wherein the array comprises N fibre-optic bus fibres extending in parallel along the length of the line array, each package i/o fibre bei…
