From equations (5.80a) and (5.80b) we realize that Since we are free to chose the I channel signal x (t ) and the Q channel signal y (t ) as we please, we can obviously perform amplitude modulation ...

The interferometric fiber-optic gyroscope (IFOG) is an instrument for rotational motion monitoring. In IFOGs, frequency modulation is required for noise suppression. However, when the modulation ...

The phase modulation depth (PMD) deviation effect substantially constrains the displacement measurement range of fiber-optic sinusoidal frequency modulation interferometer (FO-SFMI), necessitating ...
