    Abstract: A method for outputting a closest match of a plurality of electronically stored shade guide values of a dental shade guide system is disclosed. A protective tip including a hole for couples light from a probe to a measurement spot on a dental object. The probe is in proximity to a reference standard and a calibration/normalization measurement of the reference standard is taken. Light returned from the dental object is measured with an optical sensor. A first frequency proportional to an intensity of a first wavelength/spectral band of light is determined, a second frequency proportional to an intensity of a second wavelength/spectral band is determined, and a third frequency proportional to an intensity of a third wavelength/spectral band of light is determined. A closest match is selected of a plurality of electronically stored shade guide values of one or more dental shade guide systems.

    Abstract: The disclosure generally relates to a method and apparatus for compact dispersive imaging spectrometer. More specifically, one embodiment of the disclosure relates to a portable system for obtaining a spatially accurate wavelength-resolved image of a sample having a first and a second spatial dimension. The portable system can include a photon emission source for sequentially illuminating a plurality of portions of said sample with a plurality of photons to produce photons scattered by the sample. The photon emission source can illuminate the sample along the first spatial dimension for each of plural predetermined positions of the second spatial dimension. The system may also include an optical lens for collecting the scattered photons to produce therefrom filtered photons, a dispersive spectrometer for determining a wavelength of ones of the filtered photons, a photon detector for receiving the filtered photons and obtaining therefrom plural spectra of said sample, and a processor for producing a two dimensional image of said sample from the plural spectra.

    Abstract: A hand-held colorimetric device (101) suitable for use by blind or colour-blind individuals to determine the colour of a surface-under-test (SUT), for example of a fabric, has an aperture (110) which, in use, is covered by the SUT (113) whose colour is to be determined. Six LEDs (115A, 115B, 116B, 117A and 117B) arranged in pairs (115A/115B, 116A/116 B, 117a/117B) emitting red/orange, green, and blue light illuminate the SUT and diffuse reflections therefrom containing red/orange, green, and blue spectrum sample values are used to determine the luminous reflectivity and chromaticity values for the colour of the SUT. The measured values are compared with colorimetric values of reference surfaces to determine the colour of the SUT. The colorimetric device may output the name of the colour aurally.

    Abstract: Crime scene lighting devices are used in forensic criminology for illumination and investigation at crime scenes using fluorescence excitation. High radiation powers are required both for white light in the so-called general search and for the criminologically relevant UVA-blue-green range. Moreover, it should be possible for the crime scene investigator to use the forensic lighting device portably and independent from the public power supply. The present disclosure relates to a suitable crime scene light device with a mercury ultra high pressure lamp as the light source, a light guide and terminals for operating the lamp selectively with an accumulator or the public power supply system. A suitable carrier bag, a so-called lorgnette with various longpass filters and a cross-section converter for visualizing shoeprints form useful accessories of the forensic lighting device.

    Abstract: A color measurement system includes a hand held color measurement instrument, which may be provided with a wireless interface to a computer. The color measurement system includes a scanning guide for holding the hand held color measurement instrument in proper alignment with a color target. The scanning guide includes a calibration reference to allow convenient calibration of the hand-held color measurement instrument. The hand-held color instrument includes an illumination ring to provide visual feedback to the user. The color of the illumination ring changes in order to display a color similar to that being read by the hand-held color measurement instrument. Color management profiling of the hand held color measurement instrument illumination ring improves the color rendition capability of the illumination ring.
