Description
The Li-Cor Plant Canopy Analyzer sensing head has five
concentric silicon ring detectors beneath a nearly hemispherical
(150? field of view) lens. A blocking filter restricts radiation
of less than 490 nm, which minimizes the effect of light
scattered by foliage (Welles, 1990 ). The five rings provide
data at five zenith angles for use in the inversion model. A
separate dedicated controller-data logger is attached to the
sensing head and records light readings for each ring. Readings
