Photonics helps to measure faster and more reliably

Greenhouse horticulture already uses many sensors. But vertical farming, autonomous cultivation and data-driven cultivation, require equipment that is even more sensitive and accurate. Using photonics, or optical technology, makes it possible, for example, to detect diseases in crops quicker and more accurately. Within the Agro Food Robotics programme, the Greenhouse Horticulture and Flower Bulbs Business Unit of Wageningen University & Research is actively committed to the development of such sensors.

Photonics is still a fairly new field, but by now many companies and organisations – including in the Netherlands and France – are active in the field of this technology. Among other things, they focus on the development of sensors based on ‘photonics integrated circuits’ (PICs).

Equipment using photonics has been around for a long time in agriculture and horticulture: for example, spectral cameras in sorting machines, on drones or mobile platforms are used to detect defects, diseases or plant health. But more useful photonics applications for horticulture are conceivable. The question is: which applications, and which technology is required for them?

How does WUR work on de development of photonics?

Earlier this year, WUR researchers took part in a trade mission to France to explore collaboration with various companies within the Photonics cluster in Bretagne.
