Abstract

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.

Core Innovation

The invention relates to skin diagnostics by scanning a plurality of optical excitation light wavelength bands on a material sample, where the material sample exhibits optical spectral characteristics along the light wavelength spectrum. In response to the scanned excitation bands, excitation response wavelengths emitted by the material sample are captured using an imaging sensor, and the scanned excitation bands include one or more non-fluorescent optical excitation light wavelength bands.

The method measures output values of a plurality of pixels of an image from the imaging sensor, where the image represents the excitation response wavelengths captured by the imaging sensor. The measuring detects optical spectral characteristics of the material sample that are in response to the plurality of optical excitation light wavelength bands, and the measured pixel output values are interpreted to identify diagnostic compositional information.

Based on interpreting the measured output values, the invention generates an output signature indicative of composition of the material sample. The output signature includes a granulation output signature for identifying granulation of the material sample, and the signature is derived from the optical spectral characteristics obtained through the excitation and imaging sensor capture workflow.

Claims Coverage

The document contains three independent claims: one method claim and two computer-implemented claims. The independent claims cover the same core inventive workflow of scanning excitation wavelength bands including non-fluorescent bands, imaging excitation response wavelengths, measuring pixel output values, and generating an output signature that includes a granulation output signature.

Across the independent method, computer program product, and computer system claims, the inventive coverage centers on scanning multiple optical excitation light wavelength bands including one or more non-fluorescent bands, capturing excitation response wavelengths with an imaging sensor, measuring pixel output values to detect optical spectral characteristics, and generating an output signature indicative of composition that includes a granulation output signature.
