3D-Printed Hyperspectral Imagers Designed for UAVs

Facebook X LinkedIn Email
Researchers used 3D printing and low-cost parts to create an inexpensive hyperspectral imager that is light enough to use on drones. The visible-wavelength hyperspectral imager (HSI) weighs less than half a pound and, according to researchers, can be built for as little $700 (USD). In a recent paper the team provides directions for creating the HSI. Researchers used 3D printing to create hyperspectral imagers that are light enough to use on a drone. The imager is the small protrusion on the bottom of the drone's body. Courtesy of João Fortuna, Norwegian University of Science and...Read full article

    hyperspectral imaging
    Hyperspectral imaging is an advanced imaging technique that captures and processes information from across the electromagnetic spectrum. Unlike traditional imaging systems that record only a few spectral bands (such as red, green, and blue in visible light), hyperspectral imaging collects data in numerous contiguous bands, covering a wide range of wavelengths. This extended spectral coverage enables detailed analysis and characterization of materials based on their spectral signatures. Key...
    visible spectrum
    That region of the electromagnetic spectrum to which the retina is sensitive and by which the eye sees. It extends from about 400 to 750 nm in wavelength.
