Description

Technical Field

[0001] This utility model relates to the field of spectral multi-band fitting technology, and in particular to a device for full-spectrum multi-band fitting of complex water bodies. Background Technology

[0002] Water quality testing of complex water bodies (such as industrial wastewater, eutrophic lakes, and seawater) requires obtaining information such as pollutant concentration and composition through spectral analysis, with full-spectrum multi-band fitting technology being the core method.

[0003] Existing detection devices have low spectral acquisition accuracy, and single-band detection cannot cover the characteristic spectra of multiple pollutants in complex water bodies, which easily leads to missed detections or misjudgments. Environmental interference is significant, and fluctuations in external light and temperature can affect the stability of spectral data, resulting in deviations in fitting results. These problems restrict the accuracy and convenience of water quality detection in complex water bodies. Therefore, we propose a full-spectrum multi-band fitting device for complex water bodies.
