Abstract
A gravity referenced optical inclinometer which uses a transparent flu id as angle-sensor element is described. Its principle of operation is based on light refraction at a free surface of the fluid. Measurement s were carried out in an optical inclinometer built by the authors, an d a resolution of 0.007 degrees was obtained. The inclinometer permits real-time angle determinations along two perpendicular axis.
