Methods and Systems for Imaging and Modeling Skin Using Polarized Lighting
First Claim
1. An imaging system for imaging skin, comprising:
- one or more light sources configured to illuminate a subject;
one or more photodetectors configured to acquire images of the subject as illuminated by at least one of the one or more light sources;
one or more adjustable polarizers, each coupled with a respective photodetector of the one or more photodetectors and configured to provide an adjustable axis of polarization of light received by the respective photodetector;
one or more processors; and
memory storing one or more programs for execution by the one or more processors, the one or more programs including instructions for;
acquiring a first image of the subject in a first polarization with the respective photodetector;
acquiring a second image of the subject in a second polarization with the respective photodetector;
generating a subtraction image by subtracting at least a portion of the first image from a corresponding portion of the second image; and
providing at least a portion of the subtraction image for display.

Abstract
A method for imaging skin includes illuminating a subject with at least one light source of one or more light sources. The method includes acquiring a first image of the subject in a first polarization with a respective photodetector of one or more photodetectors configured to acquire images of the subject as illuminated by the at least one light source, and acquiring a second image of the subject in a second polarization with the respective photodetector. The method also includes generating a subtraction image by subtracting at least a portion of the first image from a corresponding portion of the second image, and providing at least a portion of the subtraction image for display.
