TIS. A laser speckle reduction system Joshua M. Cobb *, Paul Michaloski ** Corning Advanced Optics, 60 O Connor Road, Fairport, NY 14450 ABSTRACT Speckle degrades the contrast of the fringe patterns in laser interferometers that measure rough objects. 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 Optotoune's laser speckle reducers are nothing else than moving diffusers. But the way they are actuated is absolutely unique. Within a height of less than 1mm, electroactive polymers are used to generate an oscillating motion (e.g.

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".

Laser speckle rheology

In LSR, a blood sample is illuminated with laser light and temporal speckle intensity fluctuations are measured using a high-speed CMOS camera.

Laser speckle rheology

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. Laser speckle microrheology is used to determine a mechanical property of a biological tissue, namely, an elastic modulus.

Here, we use Laser Speckle Strain Imaging (LSSI) to create highly resolved micromechanical maps of an elastomer in the moments before the nucleation of a delayed crack. In this way, we quantitatively probe the small but distinct emergence of a zone of diverging strains that are the result of strongly localized bond rupture events. 2020-06-22 · We show that the speckle analysis provides a non-spectral way to assess the coherence of semiconductor laser light.
