Vol. 37(16), pp. 3468-3470 
DOI URL 
Abstract: Phase-shifting fringe projection is the primary structured illumination method for high-accuracy, three-dimensional (3D) shape measurements in the fields of profilometry and stereophotogrammetry. Many different schemes for the phase evaluation and the phase-shifted fringe pattern design exist. Here we focus on the role of the phase evaluation in the context of stereophotogrammetry, where the nominal phase value itself is merely used as an image feature that can be exploited to establish a correspondence between the two camera views. Starting from the classical phase evaluation function, we will discuss its essential properties for a highly accurate correspondence mapping. Based on the findings, we generalize the classical function to derive a generalized phase value for a sequence of stereo images. An experimental comparison between a correspondence assignment using the classical phase evaluation function and a specifically chosen general phase evaluation function is given.

H. Babovsky, M. Grosse, J. Buehl, A. Kiessling and R. Kowarschik Stereophotogrammetric 3D shape measurement by holographic methods using structured speckle illumination combined with interferometry 2011 Opt. Lett.
Vol. 36(23), pp. 4512-4514 
DOI URL 
Abstract: We present a unique combination of the numerical three-dimensional (3D) reconstruction of the shape of an object with interferometric deformation measurements. Two cameras record several holograms of an object that is illuminated by structured illumination. This illumination is realized by speckle patterns. To improve the image quality, an inplace speckle reduction technique is combined with the structured illumination to reduce the effect of disturbing subjective speckles which appear in the reconstructed images. Stereophotogrammetric methods are applied to extract the 3D surface information of the object out of the reconstructed images. Since the recording is done by holography and because stereophotogrammetry enables a pointwise correlation between the two views, it is possible to combine other holographic techniques with the reconstructed 3D shape. This is demonstrated by an interferometric deformation measurement of an object cooling down. The resulting interferometric fringes are mapped onto the reconstructed 3D surface. Hence, the proposed method enables automatic and dense matching of interferometric fringe-maps recorded by spatially separated holograms onto the surface of the object, which has not yet been realized by existing techniques.

M. Schaffer, M. Grosse, B. Harendt and R. Kowarschik Fast 3D shape measurements using laser speckle projection 2011 Optical Measurement Systems for Industrial Inspection VII
Vol. 8082(1)Optical Measurement Systems for Industrial Inspection VII, pp. 808219 
DOI URL 
Abstract: 3D measurement setups based on structured light projection are widely used for many industrial applications. Due to intense research in the past the accuracy is comparably high in connection with relatively low cost of the equipment. But facing higher acquisition rates in industries especially for chain assembling lines there are still hurdles to take when accelerating 3D measurements and at the same time retaining accuracies. We developed a projection technique that uses laser speckles to enable fast 3D measurements with statistically structured light patterns. In combination with a temporal correlation technique dense and accurate 3D reconstructions at nearly video rate can be achieved.

M. Schaffer, M. Grosse, B. Harendt and R. Kowarschik High-speed three-dimensional shape measurements of objects with laser speckles and acousto-optical deflection 2011 Opt. Lett.
Vol. 36(16), pp. 3097-3099 
DOI URL 
Abstract: Many three-dimensional (3D) shape measurement techniques in stereophotogrammetry with temporal coded structured illumination are limited to static scenes because the time for measurement is too long in comparison to the object speed. The measurement of moving objects result in erroneous reconstructions. This is apparent to reduce measurement time to overcome this limitation, which is often done by increasing the projection rate for illumination while shrinking the amount of images taken for reconstruction. The projection rate limits most applications in its speed because digital light processing (DLP) projectors, which are widely used, bring a limited projection rate along. Our approach, in contrast, does not take a DLP. Instead we use laser speckles as projected patterns which are switched using an acousto-optical deflector. The projection rate is 10texttimes higher than what the fastest stripe projection systems to our knowledge achieve. Hence, we present this uncommon but potential approach for highspeed ($250?3Dfps$=$ 3D measurements per second), dense, and accurate 3D measurements of spatially separated objects and show the media that emphasizes the ability of accurate measurements while the objects under testing move.
