Laser Speckle in Medical Imaging - LaserLabMed Laser speckle is an interference phenomenon that is observed when coherent light (e.g.laser ) is scattered from a diffusing surface. In general, a speckle pattern is a random pattern whose properties can be described using stochastics and probabilistic laws.

RFLSI III is based on the LSCI (Laser Speckle Contrast Imaging) technology design. With the advantages of its non-contact, high time resolution, high spatial resolution, and full-field rapid imaging, it provides a real-time dynamic blood flow monitoring and recording method for research in life sciences.

To conclude we present results that show that the speckle contrast can be reduced to C = 0.11 ± 0.02 at a temperature of 30ºC and demonstrate the improvement of the quality of an image generated using a modified commercial projector fitted with a monochromatic laser source. Laser speckle flowmetry The technique for LSF has been described in detail else-where (Dunn et al., 2001). Briefly, a CCD camera (Cohu, San Diego, CA, U.S.A.) was positioned above the head, and a laser diode (780 nm) was used to illuminate the skull surface in a diffuse manner. The penetration depth of the laser is approxi- The speckle pattern produced when a laser is scattered by a disordered medium has recently been shown to give a surprisingly accurate or broadband measurement of wavelength. Here it is shown that deep learning is an ideal approach to analyze wavelength variations using a speckle wavemeter due to its ability to identify trends and overcome low signal to noise ratio in complex datasets. Laser speckle—the dazzling pattern of light and dark spots you see here—arises from a phenomenon known as wave interference.
