Development and application of spatial carrier interferometry for whole field real-time investigation of temperatures in liquid media

Two-wavelength interferometry for measurement of transonic airflow in a compressor blade cascade

“…in order to suppress undesired optical aberration. The interference phase can be used to determine the desired physical quantity such as temperature [8], shape [9], refractive index [10], vibration amplitudes [11] or density/ isentropic Mach number [7] as in this particular case. So far, we have considered only single wavelength SCI, with the unambiguity range of the wavelength of the light.…”

Quantitative Schlieren imaging based on fringe projection

“…The measured density distribution was compared to interferometric results. In addition to the direct use of this technique in various research topics, it can also be used along with interferometry [7] of highgradient fields in order to subtract mapping error within interferometric data evaluation.…”

Digital Holographic Interferometry for the Measurement of Symmetrical Temperature Fields in Liquids

“…There is a vast field of applications of DHI and other interference based methods including: entertainment display [8], imaging heat transfer and mass transfer [7,[9][10][11][12][13], research in free convection [14,15], visualization of the 3D velocity vector field in turbulent boundary layer [6], analysis of supersonic jets [6], biological (living cell imaging) [6,16], environmental applications [6,17], precision measurements [8,18,19], small displacements [20], thermomechanical analysis and non-destructive testing [6], microscopy and high-resolution volume imagery [21,22], vibrometry [23,24], topography [25,26], process monitoring [7], computerized tomography [7,27], and so on. This paper aims at investigating heat transfer problems.…”
