Photonics has been acquired by agrifood industry only recently but nowadays the future of this industry can not be imagined without it. Self-controlling machines are already working in fields, drones are flying above fields measuring if fruits and vegetables are ready to be cropped, are analysing soil quality and what chemicals the soil is currently missing to make the production safer, better and in bigger quantities.

Photonics technologies can help to predict protein levels in wheat harvests, determine when to harvest grapes, map water quality to observe the health of fish stocks, and screen for contaminants in spinach, tomatoes, and other foods.

Ensuring that food, drink, and pharmaceuticals are all safe for consumption is another way that photonics plays an important role in enhancing life on the planet. Recent innovations in spectral imaging sensors have enabled improved food safety and food quality inspections with ruggedized in- or at-line processing monitoring and direct real-time monitoring at a high volume.

Infrared sensing  technologies now play key roles in determining the health of soil, nutrient content, and the hydrology of a particular agricultural area.
