Abstract: A photoelectric color measuring head for measuring color properties of a measurement object includes an illumination device for exposing the measurement object to illuminating light and a wavelength-range-selective photoelectric receiver device (40) which intercepts measurement light remitted by the illuminated measurement object and converts it into corresponding electrical measurement signals. The illumination device includes an essentially white light-emitting diode (30) and means (60) for defining the angle of incidence range, so that the measurement object receives light only within an angle of incidence range, standardized for color measurement applications, of preferably 45°+/−5-10°. The receiver device includes a sensor field consisting of a multitude of photoelectric sensor pixels arranged in a line and the sensor pixels are made sensitive to different wavelength ranges through previously arranged color filters (420). The sensor field is in the form of a chip and is mounted together with the light-emitting diode (30) on a shared printed circuit board (1). The color filters (420) are arranged on an elongated transparent filter carrier and mounted directly above the light inlet window of the sensor field. The sensor field is formed together with the color filters as a flat sandwich structure and surrounded by a protective frame and cast with an opaque sealing compound. The color measuring head has an extremely small structural volume and can be produced with relatively limited construction resources.

Abstract: A miniaturized diffractive imaging spectrometer (DIS) has a footprint less than 2×1 mm2, is about 2.5 mm tall (excluding an image detector, which in some embodiments may be a CCD matrix), and covers the entire visible spectral range from 400 nm to 700 nm with resolution of approximately from 2 nm to 4 nm across the field.

Abstract: A quasi-monochromatic light beam carrier for a particular telecommunication channel is likely to experience drift because of age, temperature, or other factors, and may cause the centroid wavelength of the carrier to shift. Temperature adjustments by wavelength lockers to compensate for drift on one channel may affect the performance of other channels. Embodiments of the present invention couple a quasi-monochromatic light beam through a substrate-based grating, diffract the light beam from the edge of the substrate to free space, and detect the light beam from free space at a position detector to determine the centroid wavelength based on a position of the light beam incident on the detector. The diffracted light beam may be reflected within the substrate a number of times prior to exiting the substrate towards the detector.
