Optical coherence tomography (OCT), a non-destructive imaging technique, is increasingly recognized in the field of plant biology for its potential in addressing environmental challenges in agriculture. The conventional stationary setup of OCT systems limits their application for on-site use, often necessitating plant dissection for laboratory analysis. Here we present a portable OCT system, enabling direct observation of plants in their natural environments. A possible application of this system is the monitoring of russeting in apple skin. Russeting in apples, which manifests as brown, rough patches on the skin, is promoted by several environmental factors and leads to significant economic losses, as affected apples often fail to meet market standards for sale. This not only affects profitability but also raises concerns about sustainability, as it results in increased food waste and resource inefficiency. By enabling OCT imaging on apples still on the tree, our system could offer new insights in russeting development and its dynamic interplay with environmental factors such as humidity. We detail technical aspects of our system and present preliminary results.
