    Abstract: The method and apparatus of the present invention provides a system wherein light-emitting diodes (LEDs) (162) can be tuned within a given range by selecting their operating drive current in order to obtain a precise wavelength. The present invention further provides a manner in which to calibrate and utilize an LED probe (150), such that the shift in wavelength for a known change in drive current is a known quantity. In general, the principle of wavelength shift for current drive changes for LEDs is utilized in order to allow better calibration and added flexibility in the use of LED sensors, particularly in applications when the precise wavelength is needed in order to obtain accurate measurements. The present invention also provides a system in which it is not necessary to know precise wavelengths of LEDs where precise wavelengths were needed in the past. Finally, the present invention provides a method and apparatus for determining the operating wavelength of a light-emitting element such a light-emitting diode.

    Abstract: An integrating sphere, and an integrating sphere-based reflectance colorimeter/spectrophotometer for the measurement of color and appearance, having multiple receivers capable of concurrently receiving optical radiation scattered/reflected from a diffusely illuminated sample surface, with the capability of multiple measurement modes (e.g., multiple specular component excluded (SCE), SCE and specular component included (SCI), multiple SCI), multiple areas-of-view for a given measurement mode, multiple viewing angles per measurement mode, and combinations thereof. An embodiment of the invention includes two SCI receivers and two SCE receivers, each disposed at an equal viewing angle relative to the sample surface. For each viewing mode, two sample areas-of-view are provided. The SCE receivers are opposite each other, such that the specular component of each SCE receiver is excluded by the port of the other SCE receiver. The receivers provide the collected light reflected from the sample to a detector which preferably is provided by multiple spectrometers or a single spectrometer having multichannel capability to preferably sense the light from each receiver in parallel.

    Abstract: A remote reading spectrophotometer (10) is provided having the capability to accurately measure spectral reflectance at relatively long sample distances. A first illumination optics arrangement (14) assures uniform illumination to a portion of the sample and a second optical means (20) focuses the reflected image of part of the illuminated sample onto a poly­chromator (22). Reference beam means are provided so that the polychromator sequentially measures the spectral characteristics of the reference beam and the sample. Continuous monitoring of the illumination at select wavelengths provides illumination normal­ization data so that a microprocessor (40) can normalize the illumination and compare the reference beam and sample measurements to accurately determine the spectral reflectance characteristics of the sample. Angular and raster scanning capability is also provided.
