Abstract: A device for determining the surface topology and associated colour of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing colour data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the colour data and depth data for each point in the array, thereby providing a three-dimensional colour virtual model of the surface of the structure. A corresponding method for determining the surface topology and associated colour of a structure is also provided.

Abstract: A curved mirrored surface (78) is used to collect radiation scattered by a sample surface (76a) and originating from a normal illumination beam (70) and an oblique illumination beam (90). The collected radiation is focused to a detector (80). Scattered radiation originating from the normal and oblique illumination beams may be distinguished by employing radiation at two different wavelengths, by intentionally introducing an offset between the spots illuminated by the two beams or by switching the normal and oblique illumination beams (70, 90) on and off alternately. Beam position error caused by change in sample height may be corrected by detecting specular reflection of an oblique illumination beam and changing the direction of illumination in response thereto. Butterfly-shaped spatial filters may be used in conjunction with curved mirror radiation collectors 78 to restrict detection to certain azimuthal angles.

Abstract: An apparatus (300') and method capable of providing spatially multiplexed IR spectral information simultaneously in real-time for multiple samples or multiple spatial areas of one sample using IR absorption phenomena requires no moving parts or Fourier Transform during operation, and self-compensates for background spectra and degradation of component performance over time. IR spectral information and chemical analysis of the samples is determined by using one or more IR sources (310, 311), one or more sampling accessories (330, 331) for positioning the sample volumes, one or more optically dispersive elements (350), a focal plane array (FPA) (370) arranged to detect the dispersed light beams, and a processor (380) and display (390) to control the FPA (370), and display(390) to control the FPA (370) and display IR spectrograph.

Abstract: Device and method for recording the visual properties of a surface, comprising an imaging device (3) for recording light interaction (reflection or transmission) with a surface, a light source (2), and a sample area for positioning a sample (6) with a surface to be examined. The imaging device, the light source, and the sample area are arranged in such a way that in one image at least one of the surface properties is recordable as a function of a continuous range of angles between the illumination direction (7, 9) and the observation direction (4, 5). The imaging device is a CCD camera. The device and method are suitable for imaging and evaluating visual properties which are dependent on the optical geometry, such as flop behaviour and gloss.

In other aspects, the present invention provides methods for measuring a photosynthetic parameter, the methods comprising the steps of: (a) illuminating a plant leaf until steady-state photosynthesis is achieved; (b) subjecting the illuminated plant leaf to a period of darkness; (c) using a kinetic spectrophotometer of the invention to collect spectral data from the plant leaf treated in accordance with steps (a) and (b); and (d) determining a value for a photosynthetic parameter from the spectral data.
