Measurement of temperature and temperature profile of an axisymmetric gaseous flames using Lau phase interferometer with linear gratings

Application of wavelet filtering techniques to Lau interferometric fringe analysis for measurement of small tilt angles

“…have been reported by the author. In recent times, the use of Lau effect/interferometer for measurement of focal length [2], temperature [3,4], refractive index [5], parallelism of the plate [6], degree of coherence [7], small tilt angle [8], etc. has been reported.…”

Investigation of the accuracy of different methods of interferogram analysis for calculation of local free convection heat transfer coefficient on axisymmetric objects

“…In a group of optical methods which are called index of refraction methods, the temperature distribution is obtained from variation of index of refraction or spatial derivatives of index of refraction. Holographic interferometry [1], Moiré deflectometry [2], Laser speckle photography [3], Shearing interferometry [4], Speckle Shearing interferometry [5], Talbot interferometry [6], Lau phase interferometry [7] and Mach-Zehnder interferometry are a few examples of these methods.…”

Multilayer perceptron as inverse model in a ground-based remote sensing temperature retrieval problem

“…The flame temperature appears, among others, as a very important parameter to be monitored (Romero et al, 2005;Thakur et al, 2001;Liu and Jiang, 2001;Lu et al, 2004). Usually thermocouples have been used but are intrusive and disturb the measurement, and they must undergo the harsh furnace environment also.…”
