	~~Using PDH technique to sense the vibration and the movement of the mirror driven by the noise from the environment (acoustic, thermal, etc.)~~

	PDH is commonly used in locking to provide a means to control and decrease the laser’s linewidth, and further to stabilize the mode of the laser light. Alternatively, if a stable laser is available, the PDH technique can be used to stabilize and/or measure the instabilities in an optical cavity length.

	In this proposal, we will lock the cavity by reading the error signal of reflection/transmission of the cavity and then feed it back to the input mirror, moving the mirror with a PZT. And then we can read out the cavity length change from the error signal. This sensing technique is commonly using in LVK (LIGO-Virgo-KAGRA) interferometric gravitational wave detection community, as well as quantum optomechnics.
