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.

Claim (Index 18):
A polarization difference imaging (PDI) apparatus comprising:\n a light source, an illumination optic, and a linear polarizer, that are jointly configured to emit linearly-polarized light towards a sample; a non-total internal reflection (TIR) birefringent polarizing prism (BPP) that is:\n positioned to receive a light beam reflected from the sample responsive to the emitted linearly-polarized light, and \n configured to separate the received light beam into two differently-polarized beams that exit the non-TIR BPP from two different locations; \n a sensor coupled to an objective lens, such that the two differently-polarized beams form two distinct images in two separate regions of the sensor, respective of the two different locations; and a processing unit configured to compute a PDI image of the sample from the two distinct images.
