RFLSI Ⅲ Laser Speckle Contrast Imaging System

RFLSI Ⅲ is based on the LSCI (Laser Speckle Contrast Analysis Imaging ) technology design, non-invasive with non-contact, high time resolution, high spatial resolution, and full-field rapid imaging. It provides real-time dynamic blood flow monitoring and recording for research, perfusion evaluation, such as MCAO, cerebral blood flow. compared with lase doppler  imaging, it can realize full field video imaging function.


  • Cerebral blood flow measurement, CBF, blood vascular
  • MCAO mosue/rat model
  • Cortical spreading depression (CSD)
  • Traumatic brain injury (TBI)
  • HLI/CLI, the middle ear of rodent, burn assessment, etc.

Brain Injury

“What do you think of this image, It’s that clear enough? Yes, it’s very very very nice and very impressive”
–Dr. Amar Abdullah, Ph.D.  丨 Faculty of Medicine, Dentistry and Health Sciences


Stroke & Vascular Function

“We can use the Laser Speckle Imaging System to observe the 5th branch of Mesentery.”
–Yi-Je (Jay) Chen, 丨D.V.M., Ph.D. UC Davis

Cognitive Disorder

“This is the sharpest speckle device I’ve ever seen, this is what I expected.”
–Lei P, Professor丨West China Second University Hospital
