The
LAI-2000 Plant Canopy Analyser
 The LAI-2000 calculates Leaf Area Index (LAI) and other canopy
structure attributes from radiation measurements made with a “fish-eye" optical
sensor. Measurements made above the canopy and below the canopy are used to determine
canopy light interception at 5 angles, from which LAI is computed using a model of
radiative transfer in vegetative canopies.
 Leaf area index measurements with the LAI-2000 take only a small
fraction of the time required to directly measure leaf area using conventional methods.
The cost savings for labour over the length of a research project can be substantial.
The LAI-2000 does not require direct solar beam radiation, so you do
not have to wait for a clear day, or for the sun angle to change. Further, measurements
can be made under a variety of sky conditions ; obscured sun is best, but measurements can
be made on celar days using the proper measurement technique.
