The hybrid segment is further sub-segmented into the types Embossed hologram, Integral holograms,
Holographic interferometry, multichannel hologram and computer generated hologram.
His creative and innovative work included hologram interferometry the Holo-diagram, one of the first methods to make and to evaluate
holographic interferometry fringes.
As a noninvasive and full-field measurement method, digital
holographic interferometry (DHI) has been widely used in many measurements including deformation [20-22], contour [23, 24], the field of fluid [25, 26], vibration [27,28], and microscopy [29, 30].
If the optical path difference is less than the equivalent wavelength, the real phase distribution of object can be directly obtained without phase unwrapping by the dual-wavelength digital
holographic interferometry. If the optical path difference is greater than the equivalent wavelength, the phase unwrapping process will be simplified by dual-wavelength digital
holographic interferometry.
For the validation of simulation results the
holographic interferometry setup was used.
The goal of the paper is to demonstrate the possibility of using the method of
holographic interferometry to estimate the plastic deformation in the zone of contact interaction.
His major contributions were in soft x-ray measurements of million-degree electron temperatures (he made the first "two-foil" soft x-ray electron temperature measurements), including Bragg-crystal spectroscopy; optical and laser
holographic interferometry for plasma densities and shapes; Riser scattering (for plasma electron temperature); Faraday rotation measurements of plasma magnetic fields, as well as external magnetic fields and currents using phase conjugation in single-mode optical fibers.
Holographic interferometry; a Mach-Zehnder approach.
On the other hand, digital
holographic interferometry (DHI) has become a powerful technique in modern optics.
Visualisation of temperature fields in the vicinity of heated surfaces was carried out using the method of
holographic interferometry. The obtained holographic interferogram images of temperature fields were used to determine the local values of heat transfer coefficients for a heat exchange area without protrusions and were compared with the results for a heat exchange area with triangular protrusions
His team also developed double-exposure
holographic interferometry to accurately measure high-speed phenomena resulting from shockwaves at high resolutions.
