Heterodyne Interferometer System
Speed of the light is varied with medium
So, phase difference occurred by this change of
speed of the light
Basic Interferometer System
This phase difference can be detected by square
law detector
Using this, properties of medium(µ), or thickness
of medium(?t z2-z1) can be measured
