Index matching is used in liquid-liquid and liquid-solid ([[Multiphase flow]]) experimental systems to minimise the distortions that occur in these systems <ref>{{cite journal|title=A review of solid–fluid selection options for optical-based measurements in single-phase liquid, two-phase liquid–liquid and multiphase solid–liquid flows|authors=Wright, S.F., Zadrazil, I. & Markides, C.N.|url=https://link.springer.com/article/10.1007/s00348-017-2386-y |journal=Experiments in Fluids |year=2017|volume=58 |pages=108}}</ref>, this is particularly important for systems with many interfaces which become optically inaccessible. Matching the refractive index minimises [[reflection (physics)|reflectionsreflection]], [[refraction|refractions]], [[diffraction|diffractions]] and rotations that occurs at the interfaces allowing access to regions that would otherwise be inaccessible to optical measurements. This is particularly important for advanced optical measurements like [[Laser-induced fluorescence]], [[Particle tracking velocimetry]] and [[Particle tracking velocimetry]] to name a few.
