Liquid refractometer based on immersion diffractometry.
This study presents a laser diffractometric refractometer for measuring the refractive index of liquids. The refractive index is determined by rotating a reflection grating that is immersed in the fluid under test, and measuring the first-order Littrow diffraction angle. The Littrow angle is easily detected form the interferogram formed by the diffracted beam from the grating and the reflected ...
متن کاملAn automatic interference refractometer.
Interference refractometry is a well-established method of determining the concentration of anaesthetic agents in gas mixtures. A photo-electric detector system has been fitted to a small portable, direct-reading interference refractometer to display automatically the concentration of the agent being measured. The design of the instrument is described and two possible methods of information dis...
متن کاملThe spatially resolved refractometer.
PURPOSE To investigate factors controlling the aberrations of the eye, including accommodation, wavelength, and the apodization of the optics of the eye by cone directional selectivity. METHODS We constructed a new implementation of the Spatially Resolved Refractometer (SRR). This is an instrument, based on the Scheiner principle, that allows the rapid psychophysical measurement of the comple...

متن کاملAbsolute phase birefringence dispersion in polarization-maintaining fiber or birefringent crystal retrieved from a channeled spectrum.
We report on a simple method for retrieving the wavelength dependence of the phase birefringence in a polarization-maintaining fiber or a birefringent crystal from a channeled spectrum. The method utilizes interference of polarized modes or waves resolved as the channeled spectrum and its processing by a windowed Fourier transform to reconstruct precisely the phase as a function of wavelength. ...
