Question

Which of the following is used to inspect nonlinear surfaces in very fast way in CMMs?

(a) Laser triangulation probe

(b) Impact protection

(c) Wave lasers

(d) Line laser

This question was addressed to me in an interview for internship.

My doubt is from Numerical Controlled Coordinate Measuring Machines topic in portion Measuring Machines & Total Quality Management of Engineering Metrology

Answer 1

Right choice is (d) Line laser

The best I can explain: Laser triangulation probes are used to scan the surface and after scanning it transmits a continuous flow of data. Line lasers are the fastest way to inspect non-linear surfaces. It is widely used in reverse engineering.
