Which sensor is used for hyperspectral imaging?
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.
How do you 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.
Which sensor has hyperspectral capacity?
These include hyperspectral sensors, such as AVIRIS, which have typically a hundred or more contiguous spectral channels, and multispectral sensors, such as Landsat, which typically have between three and a few tens of channels.
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 is HSI data?
Hyperspectral imaging (HSI) is a technique that analyzes a wide spectrum of light instead of just assigning primary colors (red, green, blue) to each pixel. The light striking each pixel is broken down into many different spectral bands in order to provide more information on what is imaged.
How much does a hyperspectral camera cost?
Despite the compelling ability of hyperspectral cameras to record the spectral signatures within a scene, they have found a limited market due to their lavish price tags, with costs ranging from $50K at the low end to well over $1M.
Who invented hyperspectral imaging?
NASA’s Jet Propulsion Laboratory
Hyperspectral imaging, developed by NASA’s Jet Propulsion Laboratory in the late 1970s, has become an important tool in several scientific fields, including agriculture, environmental monitoring, food processing, and cell analysis in biology.

Is hyperspectral better than multispectral?
Images produced from hyperspectral sensors contain much more data than images from multispectral sensors and have a greater potential to detect differences among land and water features.

What is the difference between hyperspectral and multispectral images?
The main difference between multispectral and hyperspectral is the number of bands and how narrow the bands are. Multispectral imagery generally refers to 3 to 10 bands. A hyperspectral image could have hundreds or thousands of bands. In general, they don’t have descriptive channel names.
How many bands are present in hyperspectral image?
Hyperspectral imaging (HSI) consists of many more than 20 bands of spectral data for each pixel.
What are the applications of hyperspectral remote sensing?
Applications of hyperspectral remote sensing range from precision agriculture to geology, environmental monitoring and archaeology.
Why IMEC hyperspectral imaging?
Imec has a long history of applying its innovative technologies to research in and from space. Our hyperspectral imaging sensors were already used in the CHIEM project that developed a novel compact hyperspectral imager – compatible with a 12U CubeSat satellite. Contact us if you want to use our sensors for your satellite projects.
