Profile measurement using a gyro (8th report)

Angle derivation without approximation

Abstract

Profile shape evaluation by detecting tangential angles of the profile is competent for evaluating large objects precisely. We consider profile evaluation using a gyro for detecting the angles. We had already proposed and demonstrated a method using a continuously rotating gyro around an axis perpendicular to its angular sensitive axis in order to eliminate its rate offset and scale factor, which are considered to be major error factors in angle detections by using gyros. Here, we consider angle derivation without approximation for the method mentioned above and evaluate it with simulations.
