Abstract

This paper describes development of a new non-contact 3-D profile sensor which is not influenced very much by inclination angles and edge profiles of 3-D free form surfaces. The proposed 3-D profile sensor called “optical ring image sensor” has two major advantages. First, reflection light from a target surface in optical axis can be detected in all directions using a ring slit. Second, the radius of optical ring image is linearly proportional to the displacement of the surface in optical axis. In this paper, a prototype of optical ring image 3-D profile sensor with unique properties mentioned above is designed and produced. From onmachine measurement using NC machine tool as well as fundamental experiments, this sensor makes it possible to measure the displacement within an accuracy of about ±7μm for the steeply inclined diffuse reflection surface up to ±80° and also about ±10μm even for a nearly specular reflection surface inclined up to ±70°. Therefore, it will be a very useful sensor for 3-D profile measurements of delicated shaped surfaces.
