Particle Imaging

Sequoia offers two instruments for particle imaging, both designed for submersible use in the ocean. The LISST-Holo2 obtains particle holograms, which are subsequently reconstructed and processed to in-focus particle images. The LISST-RTSSV uses two cameras with differing magnification to image particles ranging from 3.6 microns to 4,200 microns. In-situ particle setting velocity is measured using a built-in settling column that can be sealed off from the environment.
