Catman also allows the configuration of general FBG based transducers that
have only one FBG.

Generic optical sensor
The generic optical sensor computes the measurement as a second order
polynomial function (a, b and c coefficients) of the wavelength variation (λ-λ
0
)
of the FBG.
The reference wavelength (λ
0
) can be filled by hand or automatically defined by
an actual measurement using the
Measure
button.
