I'm trying to find some more information on plant stress detection glasses. I've found a reference to them in the media as being based on technology developed by Nasa scientists. They slip on like glasses and you are able to spot diseases before you would be able to with the naked eye.
They work by blocking out the green colour reflected by chorophyll so healthy areas of foliage appear black or grey. Stressed areas appear yellowish-brown or pink.
Does anyone know who makes or markets these glasses?
I'm not sure this is the best venue for asking this question but I tried to find something on the Nasa site and ended up in a lovely loop! Thanks for any help.
