4.1. Explanation of Important Parameters
4.1.1. About Spectral Response
QE: Which is the ratio of the average number of photoelectrons produced per unit time to the number of
incident photons at a given wavelength.
Sensitivity: The change of the sensor output signal relative to the incident light energy. The commonly
used sensitivity units are V/((W/m2) •s), V/lux •s, e-/((W/m2) •s) or DN/ ((W/m2) •s).
The spectral response graphs given by different manufacturers are different. Some graphs' ordinate is
relative sensitivity response, and abscissa is wavelength. Some graphs' ordinate is QE, and abscissa is
wavelength.
