Three-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...
متن کاملPrecision displacement measurement by active laser heterodyne interferometry.
We demonstrate an active laser heterodyne interferometer which can automatically compensate environmental disturbances and is capable of precision displacement measurement. Two Zeeman He-Ne lasers were employed. Laser II was used as the light source to stabilize the interferometer by using a piezomirror in a feedback loop. The hetereodyne signal of the two lasers was used to directly calibrate ...
متن کاملElectronic speckle pattern interferometry for simultaneous measurement of out-of-plane displacement and slope.
An optical configuration is presented for simultaneous measurement of out-of-plane displacement and slope change in electronic speckle pattern interferometry. Experimental results for a rectangular plate clamped along the edges and loaded at the center are presented.
متن کاملPicometer level displacement metrology with digitally enhanced heterodyne interferometry.
Digitally enhanced heterodyne interferometry is a laser metrology technique employing pseudo-random codes phase modulated onto an optical carrier. We present the first characterization of the technique's displacement sensitivity. The displacement of an optical cavity was measured using digitally enhanced heterodyne interferometry and compared to a simultaneous readout based on conventional Poun...
متن کاملSpeckle Interferometry and Correlation Applied to Large- Displacement Fields
A common problem in experimental mechanics is that when a sample is studied in, e.g. a tensile test machine, the sample is often simultaneously exposed to rigid body motions as small deformations occur. These two movements, the rigid body motion and the deformation, are often talked about as displacement fields. The sought deformation field is often in the micrometer range, while rigid body mot...
