title: Bi-dimensional fluid inclinometer.
abstract: A gravity referenced optical inclinometer which uses a transparent fluid as angle-sensor element is described. Its principle of operation is based on light refraction at a free surface of the fluid. Measurements were carried out in an optical inclinometer built by the authors, and a resolution of 0.007° was obtained. The inclinometer permits real-time angle determinations along two perpendicular axis.
