Speckle-based three-dimensional velocity measurement using spatial filtering velocimetry.
We present an optical method for measuring the real-time three-dimensional (3D) translational velocity of a diffusely scattering rigid object observed through an imaging system. The method is based on a combination of the motion of random speckle patterns and regular fringe patterns. The speckle pattern is formed in the observation plane of the imaging system due to reflection from an area of t...
متن کاملA High Spatial Method to Determine Three-Dimensional Velocity Gradient Tensor using Micro Particle Image Velocimetry
Micro Particle Image Velocimetry (μPIV) is a non-invasive flow field measurement technique, which is becoming the method of choice for the investigation of micro-flows. Measurements of flows which occur within the human body represent one of the most important applications of μPIV. A three-component two-dimensional scanning micro-Particle Image Velocimetry (μPIV) technique is presented in this ...
متن کاملSpeckle and fringe dynamics in imaging-speckle-pattern interferometry for spatial-filtering velocimetry.
This paper analyzes the dynamics of laser speckles and fringes, formed in an imaging-speckle-pattern interferometer with the purpose of sensing linear three-dimensional motion and out-of-plane components of rotation in real time, using optical spatial-filtering-velocimetry techniques. The ensemble-average definition of the cross-correlation function is applied to the intensity distributions, ob...
متن کاملConvective flow field measurement by speckle velocimetry
2014 A 2-D velocity map in a cylindrical Rayleigh-Bénard flow is determined by means of a speckle photography technique. Automatic velocity measurements are performed by two different methods : (i) Isovelocity contours are drawn by spatial filtering; (ii) Local illumination by a laser beam produces Young’s fringes which are analysed by an image processing system. New methods are proposed for di...
متن کاملThree-Dimensional Continuous Displacement Measurement with Temporal Speckle Pattern Interferometry
A speckle interferometer which can measure whole field three-dimensional displacements continuously and dynamically has been built. Three different wavelength lasers are used to produce the speckle interferograms of the two in-plane displacements (displacements in the x- and y-direction) and one out-of-plane displacement (displacement in the z-direction), respectively. One color CCD camera is e...
