Vibration control for optical interferometry

Develop an active vibraiton isolation platform to provide a quiet, small displacement environment for high precision inteferometry.

Dual torsion pendulum for quantum noise limited sensing

Construct a small dual tosion pendulum which have their centre of mass co-incide and their rotational axis colinear. Inital diagnostics will be done using shadow sensors.

Small-package light sources investigation for displacement sensors

Can we use small-package Vertical Cavity Surface Emitting Lasers (VCSELs) or commercial laser diodes for high-performance interferometric displacement sensors?
