3 Sensor Characterization
3.1 Spectral Response
Figure 1a shows the typical response between 350 nm and
1100 nm of an US-SQS sensor. The solid line shows the ideal re-
sponse of a photon fluence sensor for photosynthetically active radia-
tion (PAR, defined for the 400-700 nm wavelength range; for defini-
tions see chapter 7). For comparison Figure 1b, shows the absolute
response to energy fluence rate from 350-750 nm.
