Unoptimized photodetector choice leads to inaccurate plant growth facility measurements.
The goal of the study was to model errors in measuring plant growth light using a spectroradiometer. The researchers used computer software to simulate how different optical elements affect measurement accuracy. They found that choosing the wrong photodetector array and having a defocused image can lead to errors in measuring photosynthetically active radiation. The study showed that errors increase when the focal surface radius decreases and the aperture angle increases.
