Lo. Bjorn, ESTIMATION OF FLUENCE RATE FROM IRRADIANCE MEASUREMENTS WITH A COSINE-CORRECTED SENSOR, Journal of photochemistry and photobiology.B, Biology, 29(2-3), 1995, pp. 179-183
A method is described by which it is possible to measure fluence rate
(scalar irradiance) using a cosine-sensitive instrument intended for m
easurement of irradiance (vector irradiance).
