Laser speckle flowmetry (LSF) was initially developed to measure blood flow in the retina. More recently, its primary application has been to image baseline blood flow and activity-dependent changes in blood flow in the brain. We now describe experiments in the rat retina in which LSF was used in conjunction with confocal microscopy to monitor light-evoked changes in blood flow in retinal

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. © 2020 The Author (s) We have developed and investigated a novel optical approach, Laser Speckle Rheology (LSR), to evaluate a patient’s coagulation status by measuring the viscoelastic properties of blood during coagulation.

By Hajjarian Zeinab and Nadkarni Seemantini K. Cite . Speckle patterns can severely degrade the image quality of laser projection displays, or disturb position measurements with laser pointers. Speckle can often be avoided, e.g. by using a light source with sufficiently large optical bandwidth (short coherence length ) such as a superluminescent source .

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.
