RFLSI-3 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 evaluations, such as MCAO, cerebral blood flow etc. Compared with laser Doppler imaging, it can realize full field video imaging function.

The system utilizes a long life rechargeable NiMH battery pack providing more than 24-hours of run time, depending on sensor array installed. The user can also set one alarm level for each gas to activate the internal audible alarm. The system is housed in a rugged ABS enclosure with swivel handle to act as a stand support or for carrying the instrument.
