Question

Which of the following is true for checking of slip gauges with interferometer?

(a) Both ends of gauges examined simultaneously

(b) Right end is examined first

(c) Left end is examined first

(d) Any end can be examined after one another

I had been asked this question in my homework.

This is a very interesting question from Checking of Slip Gauges topic in section Testing and Calibration of Gauges and Dynamic Measurement of Engineering Metrology

Answer 1

Right option is (a) Both ends of gauges examined simultaneously

The best I can explain: The absolute measurement and gauge comparison are done by an interferometer. It consists of a higher interferometer arranged in such a way that both ends of this type of gauge are checked simultaneously in the same area of view.
