Compact All Solid State Oceanic Inherent Optical Property Sensor, Phase II

Completed Technology Project

Project Introduction

Compact All Solid State Oceanic Inherent Optical Property Sensor, Phase II
This work concerns the development of a prototype of a Volume Scattering Function (VSF) sensor for measurement of this inherent optical property(IOP) of seawater. The proposed prototype combines new development from Phase-I with our existing technology to extend existing capability for measuring VSF from 0.1 to 20 degrees, out to 170 degrees. We have developed a new and innovative sensor module that permits high sub-degree angular resolution measurement of VSF. The system is simple, yet powerful. For example, it permits programmability of the range of angles to be explored. A case is one of bubbles, which produce a bump in the VSF between 60-180 degrees. The instrument will be self-contained, internally recording, powered by batteries or external power. Beam attenuation coefficient will also be measured. The technology extends existing VSF measurement capability for benefit of NASA's interest in remote sensing. More »
