a The TERRA-REF field scanalyzer located at the Maricopa Agricultural Center. The white box suspended from the cross member houses the sensor payload including the PS2 imaging system. b The PS2 imaging system consists of a bank of light-emitting diodes (LEDs) to provide the saturating light flash. The camera is located in the center of the LED array (small black circle). c Aerial image of the 24 potted sorghum plants within the field where the scanalyzer resides courtesy of Maria Newcomb. The pots were spaced 4 m from each other in each direction and organized in a completely randomized design. Plant residue from the previous crop remained in the field
