Electrostatic field distribution measurement using silicon micro-mirror array

Electrostatic field distribution measurement using a silicon micro-mirror array fabricated by Micro-ElectroMechanical Systems (MEMS) process has been presented. The deflection of each micro-mirror by electrostatic field was measured optically using a two-dimensional optical scanner and a position sensitive detector (PSD). The obtained electrostatic data showed good agreement with Coulomb's law and the system was applied to a human body model.
