Abstract: Spectrum sensors can be continuously calibrated in a manufacturing environment employing a continuously moving platform that carries the spectrum sensors in combination with spatially separated light spectra illuminating a region of the platform. A plurality of spectrum sensors, each including multiple sensor pixels, can be placed on the platform. The spatially separated light spectra can be illuminated over an area of the platform. The plurality of spectrum sensors can be moved with the platform through a region of the spatially separated light spectrum. Each sensor pixel for each of the plurality of spectrum sensors can be calibrated based on response of each spectral channel during passage through the spatially separated light spectra. The entire spectra from a light source can be employed simultaneously to calibrate multiple spectrum sensors in the manufacturing environment.

Abstract: A measurement system includes a light source having semiconductor sources, a multiplexer, and one or more fused silica fibers configured to form an output optical beam having one or more optical wavelengths modulated at a modulation frequency. A light beam set-up includes a monochromator forming a filtered optical beam. A measurement apparatus delivers the filtered optical beam to a sample. A receiver receives a spectroscopy output beam generated from the sample by the filtered optical beam. The receiver is configured to use a lock-in technique that detects the modulation frequency, and to generate first and second signals responsive to light received while the light source is off and on, respectively. The measurement system improves a signal-to-noise ratio of the spectroscopy output beam by differencing the first and second signals. The receiver processes the spectroscopy output beam using chemometrics or multivariate analysis to permit identification of materials within the sample.

Abstract: A wearable device for use with a smart phone or tablet includes LEDs for measuring physiological parameters by modulating the LEDs and generating a near-infrared multi-wavelength optical beam. At least one LED emits at a first wavelength having a first penetration depth and at least another LED emits at a second wavelength having a second penetration depth into tissue. The device includes lenses that deliver the optical beam to the tissue, which reflects the first and second wavelengths. A receiver is configured to capture light while the LEDs are off and while at least one of the LEDs is on and to difference corresponding signals to improve a signal-to-noise ratio of the optical beam reflected from the tissue. The signal-to-noise ratio is further increased by increasing light intensity of at least one of the LEDs. The device generates an output signal representing a non-invasive measurement on blood within the tissue.
