Thread: scanning laser interferometry

A laser beam reflected from a vibrating mirror is expected to trace a uniform line. However, sometimes this uniform line splits into small parts, indicating some interference. I thank in advance for any interpretation of this unexpected observation.

Dear Kuntman,


(I warn you that William McCormick, a Scott, just like a few other members of the forum, is afoot)

Kuntman: a laser is ideally a pure beam of light: the motion you speak of, of your mirror, well..........does it match the frequency of the laser beam, and if not, why not post a subject about 'time': it's time. As you can guess, Kuntman, it's all about "timing" surface areas, which is, I am sure, one of your specialities, given how you have decided to name yourself in the fashion you have.


Sincerely,

Ghost of McCormick.
