- Abstract:
- To quantitatively determine the tip radius of spherical and conical indenters, a practical non-contact radius measurement system is presented. Realizationof the optical system has been detailed, including its theoretical and actual resolution and error sources. For the purpose of experimental investigation of the performance of the nonimaging radius measurement system, a sapphire sphere with a nominal radius of 200 µm has been employed. Detai led data analysis indicates that high-order form error of the object under test might be one of the key error sources within the calibration setup.
