    Abstract: The invention relates to a method and to an electronic circuit for processing signals which as such are indicative of the features or characteristics of the spectral distribution of light which is supplied for spectrometric measurements combined with an LED light source. The problem of the invention is to provide solutions which allow the informative value of spectrometric measurements to be increased. For this purpose, a reference curve for the spectral emission is calculated based on a reference measurement and at least two additional measurements on the same reference, said spectral emission being used as a reference when carrying out measurements of practically any objects. This curve is determined in such a manner that it corresponds to a curve of the spectral emission at a temperature that is outside or far outside the temperature range of the actual temperatures of the LED during the measurements.

    Abstract: A color measurement instrument includes a housing and illuminators, a two-dimensional photodetector array, and an optics system within the housing. A UV filter wheel closes the housing to prevent contaminants from entering the housing. The filter wheel supports UV filters and non-UV glass that can be selectively aligned with the illuminators. The photodetectors can be read in parallel, and each photodetector includes a unique spectral filter. The optics system delivers light from the sample target area equally to each of the photodetectors.

    Abstract: An object (206) to be imaged or detected is illuminated by a single broadband light source or multiple light sources emitting light at different wavelengths. The light is detected by a detector (200), which includes a light-detecting sensor (400) covered by a hybrid filter. The hybrid filter includes a multi-band narrowband filter (516) mounted over a patterned filter layer (508). The light strikes the narrowband filter (516), which passes light at or near the multiple wavelengths of interest while blocking light at all other wavelengths. The patterned filter layer (508) alternately passes the light at one particular wavelength while blocking light at the other wavelengths of interest. This allows the sensor (400) to determine either simultaneously or alternately the intensity of the ligth at the wavelengths of interest. Filters (902) may also be mounted over the light at the light sources to narrow the spectra of the light sources.

    Abstract: A handheld, portable color measuring device (10) for measuring the primary colors of red, green and blue in a color target (22) and connected to a built-in LCD display (30) or connected to a separate personal computer (38). The color measuring device (10) includes an elongated color measuring probe housing (12). A hollow cone shaped probe tip (18) is attached to one end of the probe housing (12). Inside the probe housing (12) is a battery powered white LED light source (42) connected to a color measurement switch (26). A light pipe (44) is centered inside the probe housing (12) and a portion of the probe tip (18). The light pipe (44) captures the light reflected off the color target (22) and projects the captured light onto a 3 color sensor (54). The light signal is amplified and converted to a digital signal using an A/D converter. The A/D converter is part of a microprocessor mounted on a printed circuit board (56) inside the probe housing (12).
