1. An optical sampler, comprising:
- a. An illumination subsystem, adapted to communicate light having a first polarization along a first path to a tissue surface;
b. A collection subsystem, adapted to collect light having a second polarization communicated from the tissue along a second path after interaction with the tissue;
c. Wherein the first polarization is different from the second polarization; and
d. Wherein the first path and the second path are substantially parallel for at least a portion of each path.

Abstract
The present invention provides methods and apparatuses for accurate noninvasive determination of tissue properties. Some embodiments of the present invention comprise an optical sampler having an illumination subsystem, adapted to communicate light having a first polarization along a first path to a tissue surface; a collection subsystem, adapted to collect light having a second polarization communicated from the tissue along a second path after interaction with the tissue; wherein the first polarization is different from the second polarization; and wherein the first path and the second path are substantially parallel for at least of portion of each path.
