Worldwide a lot of effort is invested in delivering fruit of the highest quality to the consumer. This means that the fruit should look good, taste good and preserve these properties for a sufficiently long period of time after harvest in order for the fruit to be of commercial value. Of course many aspects need to be considered, but here we will focus on the function of the peel. The first thing that meets the eye of the consumer is the peel of the fruit, and in many cases this is the only quality criterion that the consumer uses to ...

On the 13 th and 14 th of February 2013 the RECENDT hosted the First International Symposium on Optical Coherence Tomography for Non-Destructive Testing – OCT4NDT ( www.oct4ndt.com ) in Linz, Austria. The event was attended by around 65 researchers and company delegates from all over the world (covering 18 different countries on five different continents). During 27 talks and a poster session the different research groups had the possibility to present their work in front of an interested audience. The OCT4NDT provided a platform for the discussion of new ideas and applications and for establishing new future collaborations. Therefore the ...

Optical coherence tomography (OCT) applications in the field of non-destructive testing (NDT) have grown immensely over the past few years. In order to pave the ground for a new OCT for NDT community we are pleased to announce the First International Symposium on OCT4NDT! The symposium is intended as a get-together for people working in this field and aims at initiating new ideas and projects. . For more information please click Here .

Mechanical material testing combined with optical coherence tomography (OCT) allows for the first time the immediate detection of inner structural changes along with a qualitative observation of the local strain distribution in surface near bulk regions of semitransparent and translucent specimens. In addition to a 3D full field strain analysis (FFSA) system based on digital image correlation (DIC), a customized spectral domain OCT system operating at 1550 nm was applied for investigation. Exemplified by tensile testing of elastomer particle filled polypropylene specimens, local dissimilarity evaluation of the OCT images was performed. The results show the high potential of OCT to ...

Optical coherence tomography (OCT) is a non-invasive analysis technique allowing fast and high-quality cross-sectional imaging of scattering media. OCT is based on the physical phenomenon of low coherence interferometry and is thus well suited to image layered structures. In this paper, high-speed spectral domain OCT was used for the characterization of pharmaceutical tablet coatings, sampled at different stages of an industrial drum spray coating process, comprising tablets with a coating thickness ranging from uncoated to a target coating thickness of about 70 μm. In addition to the OCT investigation of layer thickness and homogeneity, tablet weight gain and tablet diameters ...
