REAL-TIME DIFFERENTIAL REFRACTOMETRY AT A SENSITIVITY LEVEL OF 10-6

McClimans, Michael Steven

Abstract Details

2006, Master of Science, Miami University, Physics.
We present a refractometer based on the principle of total internal reflection (TIR) that can sensitively record in real-time the refractive index of fluids over a wide range of refractive indices. The device uses a divergent laser beam and linear diode array, and has no mechanical or optical moving parts, enabling us to achieve the measurement of refractive index at a sensitivity level of 10-6. Our refractometer does not rely on interferometry, thus enabling the device to be compact, portable, and inexpensive. To the best of our knowledge, this is the first time a non-interferometric device that performs real-time differential refractometry with a sensitivity better than 10-5 has been demonstrated in the literature. We show that our experimental results agree very well with Fresnel theory. We establish a theoretical limit on the sensitivity of this class of refractometers.
