Automated monitoring in horticulture through spectral analysis with quantum dot detectors and high-resolution optical filters

23.Oct.2025   Reseach News

Researchers at Chemnitz University of Technology are working together with Fraunhofer ENAS in a European consortium on novel systems for detecting plant diseases through spectral analysis. The ZfM's contribution consists of the technological development of high-resolution optical filters in the wavelength range 0.8–2 µm and the intelligent evaluation of spectral data. Dr. Christian Helke and Prof. Karla Hiller presented the latest technological developments on September 29 in the webinar: “Technology approaches and MOEMS fabrication of NIR filter components,” which is available to the general public on the website of the “HORTIQD” project:

Further development results will be presented and discussed at the upcoming industry workshop “In-Field Spectral Sensing and Collaborative Technology Development” on November 26, 2025, from 2:00 p.m. to 5:00 p.m., in which the ZfM will also actively participate with a contribution from Prof. Hiller.

Registration for the online workshop can also be done via the project website:
