Laser Speckle Rheology for evaluating the viscoelastic properties of hydrogel scaffolds By Zeinab Hajjarian, Hadi Tavakoli Nia, Shawn Ahn, Alan J. Grodzinsky, Rakesh K. Jain and Seemantini K. Nadkarni

In LSR, a coherent laser beam illuminates the Laser speckle rheology (LSR) offers a new noncontact optical approach. LSR uses an inexpensive laser—similar to a common laser pointer to shine laser light on tissue—plus a camera to image speckle patterns reflected from light-scattering particles in the sample. Abstract We introduce a novel technology, termed laser speckle micro-rheology (LSM) that offers the unique capability to map the viscoelastic properties of the tissue microenvironment. This innovation will provide important insight into mechano-biology of disease progression.

Biomedical Optics Laser speckle rheology (LSR) offers a new noncontact optical approach. LSR uses an inexpensive laser—similar to a common laser pointer to shine laser light on tissue—plus a camera to image speckle patterns reflected from light-scattering particles in the sample. When laser light which has been scattered off a rough surface falls on another surface, it forms an "objective speckle pattern". If a photographic plate or another 2-D optical sensor is located within the scattered light field without a lens, a speckle pattern is obtained whose characteristics depend on the geometry of the system and the wavelength of the laser.

Laser Speckle Rheology (LSR) is a novel optical technology that enables mechanical evaluation of tissue. In LSR, a coherent laser beam illuminates the tissue and temporal speckle intensity fluctuations are analyzed to evaluate mechanical properties. The rate of temporal speckle fluctuations is, however, Laser speckle microrheology is used to determine a mechanical property of a biological tissue, namely, an elastic modulus. Speckle frames may be acquired by illuminating a coherent light and capturing back-scattered rays in parallel and cross-polarized states with respect to illumination. 2013-05-21 · Laser Speckle Rheology (LSR) is a novel optical technology that enables mechanical evaluation of tissue.
