Abstract

To address the need for compact and automated sensing systems in NASA's controlled-environment space crop production, we introduce "MoonLight." This innovative illumination system is tailored for hyperspectral reflectance and fluorescence imaging of plants, primarily focusing on early stress detection within the Visible and Near-Infrared (VNIR) range (400–1000 nm). Moonlight integrates white, and UVA LED arrays for VNIR broadband and 365 nm illumination alongside a line-scan hyperspectral camera and a linear motorized stage (0.5 m travel). Its design includes two parallel L.E.D. metal back substrates with narrow-angle L.E.D. lenses, ensuring a lightweight, compact system. An additional elliptical line collimator enhances spatial target line collimation while advanced thermal management maintains spectral stability, meeting the stringent demands of space missions.
