Abstract

A new experimental technique for short range gravity measurements using pico-precision displacement sensor using digital image analysis is presented. We have developed a new experimental setup using torsion balance pendulum, aiming to test the Newton's inverse square law at below millimeter scale. Weak equivalence principle can also be tested using the same experimental setup. Detector techniques and the detail of the experimental setup are described.
