Seeing greening better than the eye can

Today we were working with Ed Etxeberria and Pedro Gonzalez on a camera developed by a group of engineers at UF.  The camera uses polarized light filters to filter for starch, which accumulates in leaves affected by huanglongbing.  The camera was intended for use as a remote sensing application, but we are attempting to use it on a small scale to detect the very early onset of HLB symptoms in our studies without destroying leaves to test for the bacterium that causes it.
