Abstract: A polarized light imaging apparatus for separating light from a superficial single-scattering layer of a sample and its deeper diffuse layer as a function of space is disclosed. The apparatus has a light source for producing light beams; an illumination optic coupled to the light source for guiding the light beams towards the sample; a linear polarizer coupled to the illumination optic; a non-total internal reflection (TIR) birefringent polarizing prism (BPP) communicatively coupled to the sample to maximize a refraction difference between ordinary waves and extraordinary waves of light returning from the sample; and a detection optic unit coupled to the non-TIR BPP for guiding the light waves returning from the sample towards a single polarization sensitive sensor element.

Abstract: A system including: a mobile device, including: a camera configured to capture multiple images of a subject; a processor configured to identify a first image of the captured images as a blue frame, wherein the image was captured while the subject was illuminated by blue light, and identify a second image of one of the captured images as a white frame, wherein the image was captured while the subject was illuminated by white light; associate the blue frame with the white frame; detect a feature depicted in the blue frame that is not depicted in the associated white frame, and indicate the detection of the feature to a user; and a user interface display configured to separately render the blue frame and the white frame.

Abstract: A polarized light imaging apparatus is provided. In an embodiment, the apparatus comprises a light source for producing light beams; an illumination optic coupled to the light source for guiding the light beams towards the sample; a linear polarizer coupled to the illumination optic and configured to produce a linearly polarized light towards the sample respective of the light beams; a TIR birefringent polarizing prism (BPP) coupled to the sample to maximize a refraction difference between ordinary waves and extraordinary waves of light returning from the sample; and a detection optic unit coupled to the non-TIR BPP for guiding the light waves returning from the sample towards a single polarization sensitive sensor element (SE), the SE is configured to capture at least one frame of the sample respective of the light waves returning from the superficial single-scattering layer of the sample apart from the deeper diffuse layer.
