Abstract: A leaf imaging system is disclosed which includes a leaf-handling subsystem which includes a first leaf contactor and a second leaf contactor and configured to receive a leaf in therebetween, and an encoder coupled to one of the first or second leaf contactors, the encoder configured to selectively trigger a camera corresponding to motion of the leaf. The leaf imaging system further includes a lightbox in communication with the leaf-handling subsystem and configured to provide light to the leaf as the leaf passes between the first and the second leaf contactors; and a controller in communication with the encoder, the camera, and the lightbox and configured to operate the camera based on output of the encoder.
