Abstract:
In a method for performing a refractive index based measurement of a property of a fluid such as chemical composition or temperature, a chirp in the local spatial frequency of interference fringes of an interference pattern is reduced by mathematical manipulation of the recorded light intensity in the interference pattern or by the physical positioning and arrangement of a detector used for capturing the interference pattern.
