Can I determine the accuracy of my laser positioning measurements?

Frequently Asked Questions (FAQs)SummaryThis article introduces the basic concepts, techniques, and principles that determine the overall measurement performance of Keysight laser measurement systems.QuestionCan I determine the accuracy of my laser positioning measurements?AnswerUnderstanding the error components in the laser interferometer system will help you use the modeling technique described in this article. The measurement accuracy and repeatability is determined by summing the error components in the system’s error budgets. Before proceeding with the discussion of each component in the accuracy and repeatability error budgets, review the definitions of accuracy and repeatability given here: • Accuracy: The maximum deviation of a measurement from a known standard or true value. • Repeatability: The maximum deviation between measurements under the same conditions and with the same measuring instrument. This also refers to how stable the measurement will be over time.AttachmentsClick here to download the article.
