Publikováno v: Sensors, Vol 22, Iss 22, p 8668 (2022)

Hyperspectral imaging and distance data have previously been used in aerial, forestry, agricultural, and medical imaging applications. Extracting meaningful information from a combination of different imaging modalities is difficult, as the image sen

Publikováno v: Sensors, Systems, and Next-Generation Satellites XXV.

In October 2024, European Space Agency’s Hera mission will be launched, targeting the binary asteroid Didymos. Hera will host the Juventas and Milani CubeSats, the first CubeSats to orbit close to a small celestial body performing scientific and te

Hyperspectral imaging of asteroids using an FPI-based sensor

Autor: Hannu Laamanen, Leevi Lind, Ilkka Pölönen

The compositions of asteroids are of interest for the planetary sciences, mining, and planetary defense. The main method for evaluating these compositions is reflectance spectroscopy. Spectroscopic measurements performed from Earth can not resolve ho
