Images of root cross section are captured on remote-controlled camera while root sample is ablated by laser pulse
The Laser Ablation Tomography (LAT) system was developed by the Roots lab, including former student Ben Hall who has created a company focusing on this technique (L4IS).
Anatomical traits are measured from LAT images using a number of image analysis programs, including RootScan, a program developed by our lab.
To obtain quality images, it is important to understand the basic concepts of photography. See Photography for Beginners: A Complete Guide and Basic Principles of Photography for helpful information.

Two imaging modes have been integrated into the LAT system with a generous grant of $7,500 in Edmund Optics supplies.
