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.

Abstract: An individualized modeling equation for predicting a patient's blood glucose values is generated as a function of non-invasive spectral scans of a body part and an analysis of blood samples from the patient, and is stored on a central computer. The central computer predicts a blood glucose value for the patient as a function of the individualized modeling equation and a non-invasive spectral scan generated by a remote spectral device. If the spectral scan falls within the range of the modeling equation, the predicted blood glucose level is output to the patient. If the spectral scan falls outside the range of the modeling equation, regeneration of the model is required, and the patient takes a number of noninvasive scans and an invasive blood glucose level determination. The computer regenerates the individualized modeling equation as a function of the set of spectral scans and corresponding blood glucose values.

Abstract: A spectral characteristic measuring apparatus is provided with a memory and a CPU. The memory stores a spectral profile output from a sample light sensor array when light from a lamp is received, and a plurality of spectral profiles to be output from the sensor array at each displaced position in the case where a light separator is displaced relative to a grating member of the sensor array at a certain pitch stepwise in a wavelength diffusing direction. The CPU controls the lamp to emit light in a state that a white plate for calibration is disposed as a sample, compares a spectral profile output from the sensor array for correction with each spectral profile stored in the memory, and sets a displacement amount corresponding to the spectral profile that is most approximate to the corrective spectral profile as a wavelength shift correction amount.

Abstract: A conical illuminator for use in colorimetry, spectrophotometry, densitometry or sensitometry. In a preferred embodiment, light from a source such as a pulsed xenon lamp is integrated within a integrating chamber. The light source may be placed in a second integrating chamber adjacent to the aforementioned integrating chamber. Alternatively, the lamp may be placed directly within the integrating chamber. The light is emitted through an exit port and conformed to a conical configuration, according to a pre-selected standard, via an annular stop. An imaging optic relays the conformed light uniformly onto a sample plane. The annular stop is placed at or near the tangential focal length of the imaging optic. The annular stop may be coated with a light absorbing coating, or can be formed with a grooved or mirrored surface. Alternatively, in lieu of an integrating chamber, a diffuser may be employed for homogenizing the light. Various configurations of the imaging optic and annular stop are possible.
