    Abstract: Disclosed examples of optical systems having a plurality of light sources with each source having a different spectral outputs may be calibrated by measuring a spectral characteristic of the combined light with two measurements, e.g., one from a colorimeter and one from a sensor included in the system. Accordingly, one can determine a transform function in response to the two measures that models a feedback response of the optical system for each of a plurality of the inputs that would cause the optical system to generate radiant energy within a predetermined range of a spectrum. In order to calibrate the optical system, the transform function is programmed in the optical system to enable the optical system to transform an input to the optical system to a plurality of unique control signals each for controlling a respective light source of the plurality of light sources.

    Abstract: To determine spectra, integrated multiple illuminant measurements from a non-fully illuminant populated color sensor may be converted into a fully populated spectral curve using a reference database. The reference database is partitioned into a plurality of clusters, and an appropriate centroid is determined for each cluster by, for example, vector quantization. Training samples that form the reference database may be assigned to the clusters by comparing the Euclidean distance between the centroids and the sample under consideration, and assigning each sample to the cluster having the centroid with the shortest Euclidean distance. When all training samples have been assigned, the resulting structure is stored as the reference database. When reconstructing the spectra for new measurements from the sensor, the Euclidean distances between actual color samples under measurement and each cluster centroid are measured. The spectra are then reconstructed using only the training samples from the cluster corresponding to the shortest Euclidean distance, resulting in improved speed and accuracy.

    Abstract: A photoelectric sensor includes a light-emitting element and a light-receiving element and detects a mark on an object. Prior to the detection of the mark, a reference received light quantity level is sampled for the surface of an object not including the mark, for every color of light. A mark received light quantity level is then sampled for every color of light. The difference is obtained between the reference received light quantity level and the corresponding mark received light quantity level for each color of light. A ratio of the obtained difference to the reference received light quantity level is obtained. For the colors of light where the difference equals or exceeds a predetermined value, the color of light having the largest ratio is selected for emission from the light-emitting element in the detection of the mark.

    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: A system to provide radiant energy of selectable spectral characteristic (e.g. a selectable color combination) uses an integrating cavity to combine energy of different wavelengths from different sources. The cavity has a diffusely reflective interior surface and an aperture for allowing emission of combined radiant energy. Sources of radiant energy of different wavelengths, typically different-color LEDs, supply radiant energy into the interior of the integrating cavity. In the examples, the points of entry of the energy into the cavity typically are located so that they are not directly visible through the aperture. The cavity effectively integrates the energy of different wavelengths, so that the combined radiant energy emitted through the aperture includes the radiant energy of the various wavelengths. The apparatus also includes a control circuit coupled to the sources for establishing output intensity of radiant energy of each of the sources. Control of the intensity of emission of the sources sets the amount of each wavelength of energy in the combined output and thus determines a spectral characteristic of the radiant energy output through the aperture.
