Abstract: 1. A quasi-distributed optical fiber sensor (3) for measuring oxygen, comprising: a linear launching optical fiber (31) at center; and a probe optical fiber (32) enclosing the linear launching optical fiber (31); wherein the probe optical fiber (31) includes a plurality of sensor elements (33, 34, 35) sequentially located at its distal stretch, and wherein each sensor element (33, 34, 35) contains an oxygen sensitive nano-material and is formed by etching cladding first and then coating with the oxygen sensitive nano-material; wherein the oxygen sensitive nanomaterial in each of the plurality of sensor elements (33, 34, 35) has different fluorescence emission wavelength; and wherein the oxygen sensitive nano-materials include Tris(4,7-diphenyl-1,10- phenanthroline)ruthenium(II), Platinum(II)-5,10,15,20-tetrakis-(2,3,4,5,6- pentafluorphenyl)-porphyrin, and Palladium(II)-5,10,15,20-tetrakis-(2,3,4,5,6- pentafluorphenyl)-porphyrin. 2. The quasi-distributed optical fiber sensor (3) of claim 1, wherein the oxygen sensitive nano-materials are entrapped in an oxygen permeable and optically clear sol gel matrix for coating.
