Measurement of Air Temperature using Laser Interferometry

Estimation of supper limit canopy to air temperature differential for sugarbeet using indirect measurement of turgor potential

Measurement of corneal thickness by laser Doppler interferometry.

The laser Doppler interferometry (LDI) technique, which was recently developed for axial eye length measurement, has been modified to measure the corneal thickness of the human eye in vivo. High accuracy is achieved. The standard deviation of the technique is about 7 microns, and improvement by a factor of 5 is possible. First comparisons with a usual slit lamp pachometer show a general agreeme...

Holografic Interferometry used for Measurement of Temperature Field in Fluid

The presented paper shows the possibility of using holographic interferometry for measurement of temperature field in moving fluids. There are a few methods for identification of velocity fields in fluids, such us LDA, PIV, hot wire anemometry. It is very difficult to measure the temperature field in moving fluids. One of the often used methods is Constant Current Anemometry (CCA), which is a p...

Measurement of Bunch Length Using Intensity Interferometry

Abstract Intensity interferometry is one of the most conventional methods for measuring the length of a short light pulse (from ps to sub-ps). We attempted to apply this method to the measurement of bunch length at the Photon Factory. We tested both the second-harmonic autocorrelation method and the two-photon interference method. With both methods, we observed the autocorrelation signal of the...

Air etalon facilitated simultaneous measurement of group refractive index and thickness using spectral interferometry.

A simple method based on air etalons of a transparent cavity is proposed to simultaneously measure the group refractive index and thickness of a transparent optical plate by spectral domain low coherence interferometry. In this method, only a single beam path is needed in contrast to the two beam paths, the reference and sample arms, of the conventional Michelson interferometer. An empty cavity...
