Basically fire two lasers at right angles to each other at mirrors, and see the pattern when they bounce back.
- dekhn 11y agoBTW, you can build your own Michelson interferometer (when it was first constructed, it was a technical marvel, involving a large hunk of metal floating on mercury, deep down in a building, and even then the experiment was affected by subtle vibrations): https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=6635 https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=66...
