1) The document compares a new method of focal plane array (FPA) infrared imaging to the established synchrotron-based method for analyzing leaf tissue at a microscopic chemical level.
2) An experiment using transverse leaf sections from Eucalyptus botryoides found that the FPA method took around 2 minutes to image an area, while the synchrotron technique required approximately 8 hours to map the same area.
3) Both methods produced similar infrared images and maps that differentiated the various tissue types based on their macromolecular chemistry. While the synchrotron method had a higher signal-to-noise ratio and potentially better resolution, the FPA method had significant advantages in acquisition time,
