SMSR2
Of the highest mode peak level and the mode peaks on either side, whichever is higher
is defined as the side mode.
SMSR
Mode Peak(
L
A)
Side Mode(
L
B)
Algorithms of analysis for the SMSR1 mode are as follows.
• Perform a mode search to obtain the mode peak.
• Of the obtained mode peaks, set the wavelength value of the mode peak at the
highest level (LOG) to
λ
A.
• Of the mode peaks on either side of
λ
A, set the wavelength value at the higher level to
λ
B. If there is no mode peak other than
λ
A,
λ
B =
λ
A shall be applicable.
• Also, set the levels (linear values) for each point of
λ
A and
λ
B to LA and LB.
• Obtain SMSR and
Δλ
from the following equations.
SMSR = LA / LB
Δλ
=
λ
B -
λ
A
