    Abstract: An object 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, which includes a light-detecting sensor covered by a hybrid filter. The hybrid filter includes a multi-band narrowband filter mounted over a patterned filter layer. The light strikes the narrowband filter, which passes light at or near the multiple wavelengths of interest while blocking light at all other wavelengths. The patterned filter layer alternately passes the light at one particular wavelength while blocking light at the other wavelengths of interest. This allows the sensor to determine either simultaneously or alternately the intensity of the light at the wavelengths of interest. Filters may also be mounted over the light sources to narrow the spectra of the light sources.

    Abstract: The invention is a cable identifier apparatus and a method for fast identification of multi-wire or multi fiber cable. The method is based on illumination of colored buffer of the wire or fiber, registration the reflected light and comparison the measuring data with reference data stored in the memory. The reference data is loaded by measuring the color parameters of the buffer of known identification. The cable identifier apparatus comprises a portable hand-held device with a probe for fixing the buffer in a holder, illuminating the buffer, controlling the incident light and detecting the reflected light with photodetectors. The data is proceed by a microcontroller and an identification symbol of the buffer is displayed in LCD. The variation of the ambient light is compensated by separate measurement of dark and light signals from photodetectors.

    Abstract: An LED-based spectrophotometer uses a reconstruction algorithm, based on the spectral characteristics of the illumination source and the color sensing system, to convert integrated multiple illuminant measurements from a non-fully illuminant populated color sensor into a fully populated spectral curve using a reference database. The reference database contains training samples that indicate reflectance spectra and their corresponding LED sensor output. A dynamic, Karhunen-Loeve-based (DKL) spectral reconstruction algorithm, used to reconstruct spectra, gives greater importance to the data from the training samples in the neighborhood of the color sample under measurement. This is done using linear operators and basis vectors.

    Abstract: A handheld, pen-like colorimeter for measuring the color of an object is provided. The colorimeter includes several light emitters, each with distinct color spectra, wherein the emission of each color is modulated at a specific frequency. These light emitters may be Light Emitting Diodes (LEDs) and/or lasers. The colorimeter also contains at least one light sensor which samples light reflected from an object illuminated by the light emitters. The rate of sampling is at least twice the modulation frequency of the emitted light. A microprocessor computes the fourier transform of the intensity of the reflected light over time, wherein the fourier transform provides the light intensity at each possible modulation frequency and determines the relative contribution of the reflected light from each light emitter, as well as the contribution of ambient light. A color value is calculated and a color name is selected and presented to the user.

    Abstract: An apparatus for donor colorant detection and donor pick sensing employs N light sources of distinct wavelengths paired with N photosensors. Measured light values for a donor are combined to form an N-dimensioned coordinate value which is then compared against N-dimensioned reference values to determine a color or donor picking condition. The decision algorithm uses a decision rule based on Maximum Likelihood Decoding methods, whereby an Euclidean distance is computed between the measured N-dimensioned coordinate value and each of a set of reference N-dimensioned coordinate values. The apparatus and method detect which donor color has been picked and also detects and identifies multi-pick and pick failure conditions.
