    Abstract: A system for non-invasively interrogating an in vivo sample for measurement of analytes comprises a pulse sensor coupled to the in vivo sample for detect a blood pulse of the sample and for generating a corresponding pulse signal, a laser generator for generating a laser radiation having a wavelength, power and diameter, the laser radiation being directed toward the sample to elicit Raman signals, a laser controller adapted to activate the laser generator, a spectrometer situated to receive the Raman signals and to generate analyte spectral data; and a computing device coupled to the pulse sensor, laser controller and spectrometer which is adapted to correlate the spectral data with the pulse signal based on timing data received from the laser controller in order to isolate spectral components from analytes within the blood of the sample from spectral components from analytes arising from non-blood components of the sample.

    Abstract: A system for spectral reading includes a plurality of LEDs, an interface, and a processor. The plurality of LEDs are disposed in a physical array. Light from the plurality of LEDs is enabled to be collimated at a Fabry-Perot etalon. The interface is configured to receive a gap calibration table and power characteristics of a plurality of LEDs. The processor is configured to determine an LED switch table. The LED switch table indicates a set of the plurality of LEDs with power above a threshold at a plurality of wavelengths. The processor is further configured to cause measurement of a sample using the gap calibration table and the LED switch table for a set of gap values and determine measurement results.

    Abstract: The present invention provides a spectrometer, comprising: an inlet for the receipt of incident light; an optical path for transmitting the incident light from the inlet to an analysis plane; a focusing element located along the optical path, wherein the spectrometer has an in-focus position in which a focal point of the spectrometer and the analysis plane coincide; and a controller adapted in use, when a removable light disperser is placed along the optical path, to cause the spectrometer to be in the in- focus position by controlling the position of the focusing element relative to the analysis plane. The spectrometer is used in the analysis of light from a light source and, due to the ability of the controller to manage the focus point by way of moving the focusing element, the spectrometer is able to bring itself into an in-focus configuration without the need for a user to intervene.

    Abstract: The absolute spectral radiance of an unknown IR source is measured by bracketing the radiance measurements of the source over a spectral band with radiance measurements of a characterized blackbody at different temperatures. The absolute spectral radiance (or effective temperature) is calculated for the blackbody and paired with the relative radiance measurements. The absolute spectral radiance for the unknown IR source is derived via interpolation. The use of a characterized plate blackbody and a FTIRS allows for rapid and accurate characterization of the unknown IR source across a spectral band.

    Abstract: A laser-based spectroscopy system that combines a distance/proximity standoff sensor, a high-repetition rate laser spectroscopy system, and software with a decision-making algorithm embedded in a processing unit which in combination performs selective firing of the laser when the target object is within an interrogation zone. In a related embodiment, the system provides selective sorting of spectroscopic signals based on information from the standoff signal and from information contained in the spectral signals themselves. The laser emission can be actively controlled while keeping the laser firing, thereby preserving the thermal stability and hence the power of the laser; and the standoff sensor information and the spectral information can be combined to determine the proper relative weighting or importance of each piece of spectral information.
