Observer UHI 6
UHI: Underwater Hyperspectral Imager
The Observer UHI 6 is tailored to meet the mainstream usage pattern of the UHI technology in more shallow waters. It uses the same technology as the Scientific UHI 6 with 1936 pixels accross track, but limits the spectral range and resolution options to 400-700nm with a maximum digital spectral resolution of ~170 bands. The refraction limited optical resolution is 5.5nm.
The line sampling rates can be as high as 100Hz with full resolution, and can be increased to 200 Hz if reducing the spatial and spectral region of interest.
A video camera that works as a view finder and accompanies the hyperspectral camera is an optional add-on. The resolution is 5 MP 2592 x 1944 pixels at 5Hz but is normally configured to 648×486 at 3 Hz.
The Observer UHI can also be combined with auxillary equipment such as the SpectraLux subsea lights and an ISA500 altimeter.
