An automatic inspection method contactlessly measures the offset of a feature ofan object from a theoretical ideal center of the object and is particularly suited for, measuring at an endface of an optical fiber termination the eccentricity of an optical fiber core relative to a theoretical ideal center of the termination. The core is extremely smaller (typically between about 50 and 500 times) in size than the termination boundary.

Why it's free to use
- Filed June 13, 1996 and granted June 11, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 13, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 13, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
