Damage methodology approach on a composite panel based on a combination of Fringe Projection and 2D Digital Image Correlation
2018, Mechanical Systems and Signal ProcessingCitation Excerpt :These optical techniques are non-invasive (requiring no contact with the analysed component) and provide quantitative information on a whole surface simultaneously. Some of the most extensively employed optical techniques are Digital Shearography and Electronic Speckle Pattern Interferometry (ESPI) [26,38], Scanning Laser Doppler Vibrometry (SLDV) [25,38,39], Fringe Projection and Moiré techniques [33,34,37,40] and more recently Digital Image Correlation Technique (DIC) [28–32,35,36,41]. Among the techniques mentioned, SLDV technique are considered the most accurate and most widely employed together with accelerometers [39].
Photogrammetry and optical methods in structural dynamics – A review
2017, Mechanical Systems and Signal ProcessingCitation Excerpt :In the early stages, photograph-based speckle interferometry and holographic interferometry (HI) were developed. Using photographic plates as the recording medium can lead to very accurate results; however, the stability requirement and the time consuming data processing make them less likely to be used by industries [24]. Researchers have also used lens-less holography to perform vibration measurement in human eardrum [25].
Non-contact 1D vibration analysis in temporal digital speckle photography
2010, Optics and Lasers in EngineeringCitation Excerpt :Alternative solution is the temporal speckle pattern interferometry (TSPI) which applies the so-called time sequence phase method (TSPM) [18] in order to extract directly whole-field vibration amplitudes and phases by using conventional ESPI system without synchronization and phase shifting. Remaining sophisticated techniques use speckle decorrelation method [19], holography interferometry [20], laser Doppler vibrometry (LDV) [22] or photorefractive interferometry [21] being suitable for non-contact displacement and/or velocity measurements of the vibrating objects. In our paper we present non-contact 1D vibration analysis based on the temporal speckle photography.
