A revolutionary new camera that will detect crop disease quickly, efficiently and at a lower cost has been developed by University of the West of Scotland (UWS) academics.
The technological breakthrough, led by researchers in UWS’s Institute of Thin Films, Sensors and Imaging (ITFSI), could potentially save farmers worldwide thousands of pounds in lost produce, while increasing crop yields.
Traditional hyperspectral cameras, which can be used in agricultural management to scan crops to monitor their health, are expensive and bulky due to the nature of complex optics and electronics within the devices.
Funded by InnovateUK and the Biotechnology and Biological Sciences Research Council (BBSRC), the new camera contains a linear variable filter (LVF) developed by UWS academics Dr Shigeng Song, Dr David Hutson and Professor Des Gibson, of the University’s Institute of Thin Films, Sensors and Imaging.
The filter captures images in real time across the full visible spectrum of light, one wavelength at a time. With crops, it can highlight signs of drought stress or disease, which are difficult to detect by eye.
Dr Song, principal investigator of the InnovateUK and BBSRC-funded project, said: “Cameras like this are useful in farming and agriculture as it makes disease detection far quicker. It takes years of training, experience and time to inspect crops manually, so devices like this speed up the process.
