On-Machine Optical Probe Based on Discrete Rotational Symmetric Triangulation

In the field of modern manufacturing, probes have been playing a more and more crucial role. However, contact probes are unfit for measuring objects with soft surfaces or very tiny cavities and require radius compensation of stylus. In comparison, noncontact probes such as optical probes do not have to consider these problems and are well-performed in measurement. However...

Predictive value of procalcitonin for excluding bloodstream infection: Results of a retrospective study and utility of a rapid, quantitative test for procalcitonin
