Description
GaiaField-Pro (GFP) is a Hyperspectral Imaging Camera. It is capable of providing extremely high resolution images by scanning and taking multiple images to construct a hyperspectral datacube. GaiaField-Pro hyperspectral imaging devices obtain spatial slit spectra by projecting a strip of light from the scene onto a slit and dispersing the slit image with a prism or a grating.
Principle of Operation: Hyperspectral imaging is a spectroscopic method that collects spectral information from the imaged object rather than simply assigning discrete colors (red, green, blue) to each pixel. The light collected from each pixel is broken down into different spectral bands. Thus rich spectral information on what is imaged is collected in this fashion.
During the spatial scanning by GaiaField-Pro camera, each two-dimensional sensor output is represented as a full slit spectrum that depends both on the spatial axis and the wavelength (x, λ). The onboard integrated electronics controls the system operation, data acquisition, and analyzes.
Portability: GaiaField-Pro (GFP) Hyperspectral Imaging Camera is very portable. Such line-scan systems are particularly common in remote sensing, where mobile hyperspectral imaging platforms are desired. The system can keep working by the internal battery for ~4 hours and user can use iPad or phone to connect the camera through the internal Wifi.
Convenience: the camera connects with DJ UAV, leaving the user to only need to control the UAV by a controller to fly to the test area at a specific height. The UAV can receive the trigger signal from the operator, and the system will work and save data to the internal NUC - an onboard mini PC.

Applications
Hyperspectral Imaging Cameras have found applications in a number of domains:
Environmental: for example, to measure the water quality monitoring, or for atmospheric monitoring of the Marine environment.
Agricultural: while the initial investment can be a bit pricey, the utility of hyperspectral imaging in agriculture is by now well established. Hyperspectral remote sensing can be used to monitor the development and health of various crops. It can also be used to detect crop variety and give an early warning signal for disease outbreaks. Specialists are also looking into using these devices for detecting the chemical composition and nutritional content of plants.
Military: in military combat situations, hyperspectral imaging could provide a strategic advantage by easily detecting camouflage and enhancing the surveillance photography significantly.
Geological Research: in mineral exploration, this technique allows evaluating soil quality, as well as rapid mapping of nearly any mineral of commercial interest.
Medicine: Researchers across the globe have been working on the use of hyperspectral photography in diagnosing retinopathy and macular degeneration in early stages of disease development. In these experiments the camera detects a drop in retina oxygenation, which could indicate the onset of the ailment.
