Abstract
A method comprises: directing a laser beam onto a side of a tube, wherein the side includes a defect; moving the tube with respect to the laser beam such that the laser beam beams onto the defect; sensing a reflection of the laser beam from the side based on the defect; computationally identifying a change between the laser beam and the reflection; computationally acting based on the change. The side can be internal or external. In other implementations, the laser beam is moved with respect to the tube such that the laser beam beams onto the defect.

A method comprising:
- directing a laser beam onto an inner side of a tube from a laser source positioned within the tube, wherein the laser beam has a wavelength between about 360 nanometers (nm) and about 500 nm within a visible region of an electromagnetic spectrum, wherein the inner side includes a defect that is lubricated before an intended operative end use, wherein the inner side includes copper or an alloy including copper;
- rotationally moving the tube with respect to the laser beam such that the laser beam beams onto the defect that is lubricated before the intended operative end use, wherein the laser source is stationary within the tube while the tube is rotationally moving;
- sensing a reflection of the laser beam from the inner side based on the defect;
- computationally identifying a change between the laser beam and the reflection;
- and computationally acting based on the change.
