Twisted superfluids in moving frame
, 2020 {Helical waveguide filled by superfluid is shown to transform the linear displacements of reference frame $\vec V$ into rotations of atomic ensemble and vise versa rotations of reference frame $\vec \Omega_{\oplus}$ are the cause of linear displacements ...

Topological transformations of speckles
, 2019 Deterministic control of coherent random light is highly important for information transmission through complex media. However, only a few simple speckle transformations can be achieved through diffusers without prior characterization. As recently shown,

Beam-modulation methods in quantitative and flow visualization holographic interferometry [PDF]
This report discusses heterodyne holographic interferometry and time-average holography with a frequency shifted reference beam. Both methods will be used for the measurement and visualization of internal transonic flows, where the target facility is a ...

Residual Stress Measurement by Electronic Speckle Pattern Interferometry [PDF]
, 2007 The existence of residual stresses affects both safety and lifetime. Thus the determination of these stresses is very important. The ESPI (Electronic Speckle Pattern Interferometry) and Hole- Drilling combined method seems to be an appropriate technique ...

PISCO2: the new speckle camera of the Nice 76-cm refractor
, 2014 We present the new speckle camera PISCO2 made in 2010-2012, for the 76-cm refractor of C\^ote d'Azur Observatory. It is a focal instrument dedicated to the observation of visual binary stars using high angular resolution speckle interferometry techniques

Damage accumulation near the cold-expanded hole due to high-cycle fatigue by crack compliance method
Fracture and Structural Integrity, 2021 The novel destructive method is implemented for quantitative assessment of fatigue damage accumulation in the stress concentration zone accompanied by residual stress due to cold expansion of the through-thickness hole. Damage accumulation is reached by
