Abstract: A detecting system for detecting flaws in a sample (310) comprises an illumination assembly (320, 322) and detecting assembly (350, 354). The illumination assembly has an infra-red light source (320) and illumination optics (322) for directing a beam of light from the light source to a spot (346) on or within a sample. The detection assembly has a detector (354) for detecting light from an illuminated spot on or within a sample and detection optics (350) for directing light from an illuminated spot on or within a sample to the detector (354). Such a system may be used for determining flaws in a sample such as a thermal barrier coating on a turbine blade, or a dental or other medical part. In particular the system may be used for determining, flaws in a ceramic sample. A method for detecting flaws in a sample is further described.

Abstract: A method of assessing the fit between a dental restoration and the tooth or tooth part on which the restoration sits. The method comprises in any suitable order the steps of , obtaining a digitised representation of a surface of the tooth or tooth part, obtaining a digitised representation of a surface of the restoration which is for co-operation with the surface of the tooth or tooth part, and determining a best fit position by comparing the digitised representation of the surface of the tooth or tooth part with the surface of the restoration in a plurality of different relative positions taken in a first degree of freedom. The step of determining the best fit position is subject to the condition that there is no interference between the surface of the tooth or tooth part and the surface of the restoration.
