Abstract: A spectroscopic assembly may include a spectrometer. The spectrometer may include an illumination source to generate a light to illuminate a sample. The spectrometer may include a sensor to obtain a spectroscopic measurement based on light, reflected by the sample, from the light illuminating the sample. The spectroscopic assembly may include a light pipe to transfer the light reflected from the sample. The light pipe may include a first opening to receive the spectrometer. The light pipe may include a second opening to receive the sample, such that the sample is enclosed by the light pipe and a base surface when the sample is received at the second opening. The light pipe may be associated with aligning the illumination source and the sensor with the sample.

Abstract: A multi-sensor device may perform an optical measurement using an optical sensor of the multi-sensor device, where the optical measurement is performed when a surface of the multi-sensor device is in contact with a human body. The multi-sensor device may perform another measurement using at least one other sensor of the multi-sensor device, where the other measurement is performed when the surface of the multi-sensor device is in contact with the human body, where the other measurement is performed substantially contemporaneously with the optical measurement, and where the optical measurement and the other measurement relate to health parameters. The multi-sensor device may determine a combined measurement value based on the optical measurement and the other measurement.

Abstract: A lightpipe is coupled to a spectrometer based on a laterally variable optical filter. The lightpipe may be used for both guiding the illuminating light towards a sample and collecting light reflected or emitted by the sample upon illumination, for spectral measurements at a distance from the sample afforded by the lightpipe. The lightpipe may include a slab of homogeneous transparent material for unconstrained bidirectional propagation of light in bulk of the material. The lightpipe may be solid, hollow, or sectioned for separated guiding of the illuminating and the reflected light.

Abstract: A portable spectrometer device includes an illumination source for directing at a sample, and a tapered light pipe (TLP) for capturing light interacting with the sample at a first focal ratio and for delivering the light at a second focal ratio lower than the first focal ratio. A linearly variable filter (LVF) separates the captured light into a spectrum of constituent wavelength signals; and a detector array, including a plurality of pixels, each of the plurality of pixels disposed to receive at least a portion of a plurality of the constituent wavelength signals provides a power reading for each constituent wavelength. Preferably, the TLP is lensed at one end, and recessed in a protective boot with stepped inner walls. The gap between the TLP and LVF is minimized to further enhance resolution and robustness.
