1. A method of analyzing tissue, comprising:
- inserting a probe into tissue;
impinging radiation upon the tissue;
obtaining a sample signal of the radiation from the tissue; and
determining a refractive index of the tissue from the sample signal;
wherein the probe comprises;
a housing,a piercing tip, at a distal end of the housing,a groove, in the housing,a radiation source, anda radiation collector,wherein an optical path extends across the groove between the radiation source and the radiation collector.

Abstract
A method of analyzing tissue includes inserting a radiation source into tissue, impinging radiation upon the tissue, obtaining a sample signal of the radiation that impinges upon the tissue, and determining a refractive index of the tissue from the sample signal. The method may also include determining at least one other optical property of the tissue. The method may provide for identifying tissue as part of a biopsy method. A device for analyzing tissue may include a low-coherence interferometer and a probe optically coupled to the interferometer, where the probe includes a radiation source.
