What optical instruments are used to measure parts in aviation manufacturing?

In aviation manufacturing, there are mainly the following optical instruments used to measure parts:

Optical microscope: used to observe and measure the size and shape of tiny parts, which can enlarge the object for more accurate measurement.

Optical projector: project the image of the part onto the screen, so as to measure its size and shape more conveniently.

Optical measurement system: using computer technology, combined with optical microscope and projector, automatic measurement is realized, and the measurement efficiency and accuracy are improved.

These optical instruments are widely used in parts processing, assembly and inspection in aviation manufacturing, and play an important role in ensuring the quality and performance of aircraft.
