Sequoia: Hyper-bb – Hyper-spectral backscatter instrument

Optical Volume Scattering Function and Depolarization Sensor

Categories: , Tag:

The Hyper-bb is a submersible single-angle backscattering instrument with configurable spectral channels. The primary measurement delivered by the Hyper-bb is spectral backscattering over the wavelength range 430 nm to 700 nm. In addition to measuring spectral backscattering, the Hyper-bb also has high-performance depth and temperature sensors. Data collected with the Hyper-bb is saved onboard the instrument in non-volatile microSD memory which can be later downloaded via the Hyper-bb software.
