Abstract

A proposal method based upon laser technique for measuring dip—angle of curved railroad is presented. In this method, a miniature solid-state laser is used as a pointer whose direction can be persisted permanently perpendicular to the earth by a simple gyroscope. The dip-angle of railroad is calculated by the readings of the pointer.
