Sensing Position With Approximately Constant Contact Force
Author and Affiliation:
Sturdevant, Jay(Hughes Aircraft Co.)
Abstract: Computer-controlled electromechanical system uses number of linear variable-differential transformers (LVDTs) to measure axial positions of selected points on surface of lens, mirror, or other precise optical component with high finish. Pressures applied to pneumatically driven LVDTs adjusted to maintain small, approximately constant contact forces as positions of LVDT tips vary.
