Refractometry and Interferometry of Living Cells*†

Journal of the Optical Society of America, 1957
The development of phase contrast and interference microscopy has focused attention on the possibility of measuring the refractive indexes of living cells. Difficulties are encountered in applying immersion methods of refractometry to living cells because the choice of immersion media is very limited.

Three-dimensional rainbow refractometry

Optics Letters
We propose a new, to the best of our knowledge, rainbow technique called three-dimensional rainbow refractometry (TDRR), with a cylindrical lens in the signal collecting system. With a TDRR model based on the ray transfer matrix developed, it is proved that the tilt angle of the rainbow signal is related to the axial position of the droplet, which ...

Refractometry of fluids in microscopic tubes

Applied Optics, 1979
Fluid filling a tube immersed in a medium that matches the index of the tube acts as a cylindrical lens. Because of geometrical aberrations, the focal length cannot be used directly for an accurate determination of refractive index. By observing the focal position with a microscope that has an aperture regulating diaphragm in the back focal plane, the ...

Absorption digital refractometry

Annual Meeting Optical Society of America, 1987
This paper describes the measurement of the refractive index and the absorption coefficient of optical materials, e.g., metals and semiconductors, by a new method which we call absorption digital refractometry. This method rests on the simplification in Fresnel’s equations for reflection and the existence of high-resolution digital voltmeters.
