Overview

Swordfish software records images from the camera at the rate of up to 16 frames per second, reconstructs them and then detects and counts particles within a volume of water. It automatically counts, images and analyzes particles in water from 1 micron to 2 millimeters in size. The particle size distributions can be obtained for the measured particle populations.

The Swordfish software can:
– Detect and measure microorganisms such as algae or zooplankton within the water column
– Detect particular matter and floc
– Detect oil and gas bubbles
– Detect particles in the industrial solutions, in food or pharmaceutical applications

Applications

Benefits

Faster
Image based rapid particle detection up to 16 frames per second

Larger Sample Volume
Detect more particles than with traditional microscopy

Fast towing
Laser strobe duration down to 500 ns (on supported instruments) allows recording at towing speeds up to 4 knots

More Control
Advanced particle detection criteria, including size, intensity, threshold and shape (round & non-round)

Better Remediation
Exclusively detect oil droplets and gas bubbles in water

Versatile
Open data formats allowing exchange of information

Sample Rate Choices
Produce particle size distributions at sample rates from 1 second to 1 hour.
