摘要： Disclosed techniques include multispectral sample analysis using fluorescence signatures. At least one fluorescence excitation light wavelength is provided to a material sample. The material sample exhibits fluorescence characteristics along the Red-Green-Blue (RGB) light wavelength spectrum. The at least one fluorescence excitation light wavelength includes a wavelength less than a wavelength of the RGB light wavelength spectrum. Output values of an RGB sensor are measured. The measuring detects the fluorescence characteristics of the material sample. The fluorescence characteristics are in response to the at least one fluorescence excitation light wavelength. The output of the RGB sensor is compensated based on an analysis of a wavelength response of the RGB sensor. An indication of composition of the material sample is generated. The indication is based on interpreting the output values that were measured. The indication can include skin assessment or wound assessment, taken over time.

摘要： Disclosed techniques include skin diagnostics using optical signatures. A plurality of optical excitation light wavelength bands is scanned on a material sample, wherein the material sample exhibits optical spectral characteristics along the light wavelength spectrum. Excitation response wavelengths emitted by the material sample are captured in response to the plurality of optical excitation light wavelength bands, wherein the capturing is accomplished using an imaging sensor. Output values of a plurality of pixels of an image from the imaging sensor are measured, wherein the image represents excitation response wavelengths captured by the imaging sensor, wherein the measuring detects optical spectral characteristics of the material sample, and wherein the optical spectral characteristics are in response to the plurality of optical excitation light wavelength bands. An output signature indicative of composition of the material sample is generated, wherein the output signature is based on interpreting the output values that were measured.

摘要： Disclosed techniques include image analysis using skin wound factors. One or more skin wound images are obtained for an individual. The skin wound images provide light spectrum information that includes fluorescence and reflectance characteristics. The light spectrum information includes infrared thermal characteristics. Processors are used to analyze the skin wound images to determine metrics for skin wound factors, based on the light spectrum information. The skin wound factors comprise infection, inflammation, granulation, topology, and epithelialization. An epithelialization metric is included in determining skin wound topology. The skin wound topology comprises wound area, wound volume, wound depth, wound shape, wound edge definition, or wound topography. An output indicative of biophysical skin wound status is generated. The output is based on the analyzing of the skin wound factors. The output is augmented, based on analysis of the infrared thermal characteristics. A skin wound care plan is developed, based on the output.
