Abstract: Embodiments of the systems can be configured to receive electromagnetic emissions of a substrate (e.g., a build material of a part being made via additive manufacturing) by a detector (e.g., a multi-spectral sensor) and generate a ratio of the electromagnetic emissions to perform spectral analysis with a reduced dependence on location and orientation of a surface of the substrate relative to the multi-spectral sensor. The additive manufacturing process can involve use of a laser to generate a laser beam for fusion of the build material into the part. The system can be configured to set the multi-spectral sensor off-axis with respect to the laser (e.g., an optical path of the multi-spectral sensor is at an angle that is different than the angle of incidence of the laser beam). This can allow the multi-spectral sensor to collect spectral data simultaneously as the laser is used to build the part.

Abstract: An integrated radiation sensor for color matching functions comprises a plurality of color matching channels, each color matching channel comprising a radiation sensing element and an associated optical filter defining a spectral sensitivity profile corresponding to a color matching function. The sensors comprise a plurality of compensation channels, each compensation channel comprising a radiation sensing element and an associated optical filter defining a spectral sensitivity profile for use in compensating a color sensed by the color matching channels. The spectral sensitivity profile of each compensation channel substantially corresponds to a mean of an upper deviation spectra and a lower deviation spectra, wherein the upper deviation spectra corresponds to a spectral sensitivity profile of a typical color matching channel increased by a fixed deviation in wavelength and the lower deviation spectra corresponds to the spectral sensitivity profile of the typical color matching channel decreased by the fixed deviation in wavelength.

Abstract: An apparatus includes an integrated sensor module for detection of chemical substances. The sensor module includes a UV radiation source operable to emit UV radiation onto a sample. The sensor module also includes a sensor including dedicated channels disposed so as receive UV radiation reflected by the sample. Each of the channels is selectively sensitive to a different respective portion of the UV spectrum; collectively, the channels cover at least part of the UV spectrum sufficient for reconstruction of a spectral curve of the sample. An electronic control unit can be used to identify a composition of the sample based on signals from the channels.
