|Title:||Low-cost precision rotary index calibration||Authors:||Ng, T.W.
|Issue Date:||2005||Citation:||Ng, T.W.,Lim, T.S. (2005). Low-cost precision rotary index calibration. Proceedings of SPIE - The International Society for Optical Engineering 5879 : 1-8. ScholarBank@NUS Repository. https://doi.org/10.1117/12.614783||Abstract:||The traditional method for calibrating angular indexing repeatability of rotary axes on machine tools and measuring equipment is with a precision polygon (usually 12 sided) and an autocollimator or angular interferometer. Such a setup is typically expensive. Here, we propose a far more cost-effective approach that uses just a laser, diffractive optical element, and CCD camera. We show that significantly high accuracies can be achieved for angular index calibration.||Source Title:||Proceedings of SPIE - The International Society for Optical Engineering||URI:||http://scholarbank.nus.edu.sg/handle/10635/75297||ISSN:||0277786X||DOI:||10.1117/12.614783|
