Stupid question, but how far can you get with a laser, a mirror, and a light sensor?

- richjdsmith 2y agoThat's actually a really cool idea. I am not sure what variance there would be on a light sensor though.
- pavel_lishin 2y agoI remember building a toy interferometer in high school - a laser, splitter and a mirror. You could definitely see the interference patterns when you'd press on a wall with a finger. Maybe something like that could be turned into a reasonable microphone?
