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. The transmissive laser speckle imager is an instrument where the laser source is opposed to the detector instead of alongside.
Dynamic laser speckle as a detrimental phenomenon in - GUP
These applications include interference with scattered light, optical processing of images, and studies of surface roughness as well as displacements and deformations of diffuse objects. called speckle.

The application of a speckle pattern to the surface of a structure is usually required for Digital Image Correlation (DIC)-based displacement identifi… Laser speckle is a granular pattern formed by the interference of coherent laser light scattered from tissue . Speckle fluctuations arise from and are modulated by the Brownian motion of endogenous light scatterers and are in turn closely related to the viscoelastic properties of the tissue microenvironment [ 21 , 25 – 30 ]. A laser speckle pattern will develop behind the scattering medium as a result of the mutual interference of multiple scattering paths 12. The speckle intensity is randomly distributed, Static laser speckle suppression using multimode fibers has practical limitations as the technique requires an extremely long fiber to achieve an acceptable speckle contrast.
Laser speckle imaging can be used to study dynamic processes in turbid media, such as blood flow embedded in tissue, but it is difficult to obtain quantitative information from this technique. This paper presents a computational model for simulating the imaging process, which will be useful to further develop it as a quantitative tool for biomedical and other applications.
