A Measurements with the LAI-2200 will be much quicker than with a line quantum sensor. A typical measurement with the LAI-2200 takes less than one minute for a short canopy. The line sensor technique relies on direct solar radiation and necessitates waiting for the sun angle to change in order to determine canopy interceptance at several angles. Or, if you assume an extinction coefficient (leaf angle distribution), a line quantum sensor can be used at one angle. The LAI-2200 looks at 5 angles simultaneously for each measurement. The sample size when using the line sensor technique is limited, since the sensor only samples the portion of the canopy that lies between the sun and the sensor. With its fisheye field-of-view, the LAI-2200 can see 360° (with no view cap). Lastly, the LAI-2200 calculates LAI immediately after the measurement, allowing on-site inspection and verification of the data.
