Lisst HOLO

The LISST-Holo from Sequoia is the world’s first commercially available submersible Digital Holographic Particle Imaging System. 


The system was developed by Dr. Alex Nimmo Smith at the Marine Institute of the University of Plymouth (UK) and Sequoia holds a world-wide license for manufacture.


The LISST-HOLO is particularly well suited to the measurement of large, complex flocs and biological particles. However, existing users are also using the unit to investigate frazil ice formation. Others are considering use of the LISST-HOLO to measure the size distribution and concentration of falling snow flakes in situ.
