1. A method of analyzing a tissue structure, comprising:
- illuminating the tissue structure with at least one of a coherent light or a partially coherent light from a light source onto the tissue structure;
receiving a further light reflected from the tissue structure and forming a series of speckle patterns based on the further light; and
obtaining speckle pattern data from the series of speckle patterns at time intervals sufficient to measure a microscopic motion within the tissue structure or within a tissue adjacent to the structure; and
assessing the tissue structure by analyzing spatial characteristics of the speckle pattern data, and determining at least one of structural characteristics or biomechanical characteristics of the tissue structure which is in vivo tissue based on the assessment of the tissue structure.

17. A method for analyzing tissue, comprising:
-
illuminating the tissue with at least one of a coherent light or a partially coherent light from a light source onto the tissue; receiving a further light reflected from the tissue and form a series of speckle patterns based on the further light; and analyzing changes in the speckle patterns at time intervals sufficient to measure changes caused by a microscopic motion of objects within the tissue which is in vivo tissue.
