Patent ID: 8315692

Claim:
An instrument for detection of skin cancer comprising: a multi-spectral illumination source configured to simultaneously illuminate a two-dimensionally dispersed area over a region of skin; a solid-state image sensor configured to provide multi-spectral sensitivity over a contiguous area; a dispersion element; an optical system positioned with respect to the solid-state image sensor to receive light from the illuminated region of skin over the two-dimensionally dispersed area and configured to optically remap the light from the two-dimensionally dispersed area onto a plane as discontiguous regions dispersed in two dimensions over the plane, absent the dispersion element, wherein the image sensor is positioned at and aligned with the plane and the discontiguous regions are produced simultaneously; wherein the dispersion element is positioned between the image sensor and the optical system and configured to project spectra of the light from the skin, the spectra extending outside of the discontiguous regions; a non-transitory computer readable medium configured with instructions to analyze the spectra to identify cancerous features; and an image processor circuit configured to receive the spectra and operating to execute the instructions to analyze the spectra at multiple points over the illuminated region of skin to identify cancerous features.
