high-sensitivity, for oil slicks
CRAB is an easy-to-operate, active oil slicks optical detector. The instrument detects the presence of oil using optical sensing with a vertical laser beam and measuring the differences in the reflection properties of water and oil products.
The optimized optical scheme, signal processing routine, and modulation of the light beam intensity provide a drastic decrease of the influence of the wind waves and background illumination on the measurement results.
METHOD: Remote optical sensing of water surface with vertical laser beam.
PRINCIPLE OF OPERATION
Is based on the difference in light reflection from water and oil film surface.
Monitoring of water surfaces (sea, harbors, lakes, rivers)
Oil leakage detection
Monitoring of process and waste waters
