What is hyperspectral cube?

Hyperspectral cubes are generated from airborne sensors like NASA’s Airborne Visible/Infrared Imaging Spectrometer (AVIRIS), or from satellites like NASA’s EO-1 with its hyperspectral instrument Hyperion. However, for many development and validation studies, handheld sensors are used.

Who uses hyperspectral imaging?

Resonon’s hyperspectral imaging systems are used in food research and industry to identify defects, characterize product quality, and locate contaminants.

What is a hyperspectral imaging system?

Hyperspectral Imaging is a spectroscopic technique that collects hundreds of images at different wavelengths over a linear spatial area. The aim of hyperspectral imaging is to collect spectra for each pixel in the sample, with the purpose of identifying objects and processes.

What can hyperspectral imaging detect?

HSI detects cancers by measuring the absorption, fluorescence emission or reflectance spectrum of tissues. Additionally, there exist some multi-model designs, such as a combined reflection and fluorescence imaging system (28).

Where can I get hyperspectral images?

Hyperspectral images can be obtained from many different electromagnetic measurements. The most popular are visible (VIS), NIR, middle infrared (MIR), and Raman spectroscopy.

When was hyperspectral imaging invented?

Hyperspectral imaging of the Earth had its origins at the NASA Jet Propulsion Laboratory (JPL) following the 1972 launch of Landsat 1 (at the time called Earth Resources Technology Satellite, or ERTS 1).

How do you get hyperspectral images?

What is the difference between an RGB image and a hyperspectral image?

In contrast to the traditional RGB imaging, the hyperspectral imaging captures information from across the electromagnetic spectrum instead of just RGB, including the spatial information of each pixel. Due to the spectral signatures of each pixel, detecting objects, light, and processes become much easier.

How many hyperspectral satellites are there?

There exist at least 25 hyperspectral imagers that have been deployed into space. Among them, 19 are aboard satellites orbiting earth. Six of them are out of earth orbits for Moon, Mars, Venus, and comet missions.

Which satellite imagery is hyperspectral?

Two (2) Jilin-1 Hyperspectral Satellite sensors were successfully launched on January 21, 2019 from the Jiuquan Satellite Launch Center. Jilin-1 Hyperspectral Satellites are a part of the Jilin-1 satellite constellation and will provide high resolution satellite imagery of 5 meters with 28 hyperspectral bands.
