Abstract
A method is disclosed for changing an optical path length through a fluid downhole, comprising interspersing an optically transmissive member into a first optical path through the fluid, thereby creating a second shorter optical path through the fluid. In another embodiment, the method further comprises measuring an intensity of light, Itransmitted through the first optical path; measuring an intensity of light, Itransmitted through the second optical path; and estimating an optical property for the second optical path from the ratio, I/I. A system is disclosed for changing an optical path length through a fluid downhole, comprising a fluid passage between two optically transmissive windows for the fluid downhole, the fluid passage having a first optical path through the fluid; and an optically transmissive member for insertion into the first optical path, thereby creating a second shorter optical path through the fluid.
