Claim 9:
10. The detection device of claim 1, wherein the light adjustment module comprises a first light adjusting means that generates the first polarized light and the second polarized light such that there is a preset shear amount between the centers of the first polarized light and the second polarized light, and the first polarized light is reflected by the surface of the component to form the first echo light, the second polarized light is reflected by the surface of the component to form the second echo light, and the first and the second echo lights are combined;
and further including a polarization controller that modulates the polarization directions of the first echo light and the second echo light, so that the first echo light and the second echo light are interfered to form the signal light.
