ABSTRACT:
Apparatus for measuring force and displacement by measuring Moire fringe fts in response to relative movement between a pair of mirrors which reflect light beams therefrom to an interaction region. A pair of electro-optical sensors is positioned to view the interference region and detect fringe shifts responsive to relative movement between the mirrors.
