    Abstract: An optical characterisation system is described for characterising optical material. The system typically comprises a diffractive element (104), a detector (106) and an optical element (102). The optical element (102) thereby typically is adapted for receiving an illumination beam, which may be an illumination response of the material. The optical element (102) typically has a refractive surface for refractively collimating the illumination beam on the diffractive element (104) and a reflective surface for reflecting the diffracted illumination beam on the detector (106). The optical element (102) furthermore is adapted for cooperating with the diffractive element (104) and the detector (106) being positioned at a same side of the optical element (102) opposite to the receiving side for receiving the illumination beam.

    Abstract: A color measurement device (100) includes an error detection function for color printing control. The color measurement device includes an optical measurement head (102), the optical measurement head being moveable linearly along a color bar region (108) of a printing sheet (104), and being configured for making color measurements with respect to the color bar, and for detecting color measurement errors by determining whether such color measurements are being made at least in part with respect to regions of the printing sheet other than the color bar region. The optical measurement head may further include a pixel array (116) for tracking a center trajectory of the color bar for purposes of detecting the color measurement errors, and a color measurement engine for purposes of making the color measurements with respect to the color bar. The color measurement device may further include a motion control element (612) and a mechanical track (610) to guide the optical measurement head along the color bar region.

    Abstract: An apparatus for displaying chemical projects a chemical image of an object back onto that object. At region 23 light travels from the object to the apparatus 20 and back from the apparatus as it projects onto the object. Light 24 from the object 22 (which is illuminated by natural light) passes through an objective lens 31 of the apparatus. In its path is rotating mirror 25 and when the mirror is parallel to the path of the rays of light 24, the light is allowed to pass on to hyperspectral camera 26 which is of the AOTF type. The output from the camera is transmitted to processor 27 where the chemical image is generated from the hyperspectral data. The camera generates a series of monochromatic images that are passed to the processor and the chemical image is built up as the camera scans through the appropriate wavelengths. The image data is then transmitted to a projector 28 whose output image is focussed by lens 30 towards the rotating mirror 25. When the mirror is in the position illustrated, the image is reflected off the mirror and back through lens 31 to the imaged object 22.
