  • Primary Sector

Bessel beams offer a new approach to sensing. This programme will carry out research to develop a prototype for the “on-the-hoof” livestock body condition sensor. This will be a valuable stock management tool for production, livestock health and nutrition, and will be developed in collaboration with our industry partner.

Bessel beams are narrow, non-divergent beams of light, radio waves or sound, and a relatively new discovery. The research will extend knowledge of how Bessel beams behave, as well as how they can be used to provide high-resolution measurements. The estimated market internationally for body condition sensors is $33m per year by 2025. More importantly, understanding Bessel beams will open up a wide range of potential future applications including measuring fruit and vegetable yield, the internal quality of trees and identifying buried objects. It will also place New Zealand at the forefront of this emerging field of knowledge and its application. This research is being undertaken in collaboration with the University of Waikato, and the University of Nice (France).
