How To: Make a Laser Espionage Microphone
- chmac 19y agoThat is deeply awesome. Only of use if you want to listen to a window that you can hit almost perfectly straight on though. They have the two components at quite an angle, that wouldn't be practical if you were trying to be discreet...
- andreyf 19y agoIf I remember right from high school physics class, hitting it at a greater angle will get you a better reflection, and hence better sound quality.
- ivankirigin 19y agoTime to buy an IR laser to really fool all but the most observant.
- ivankirigin 19y agoI suppose aiming might be hard, but getting a camera that sees low res IR shouldn't be too hard. Some IR lasers http://www.nvginc.com/irlasmod.htm http://www.nvginc.com/irlasmod.htm
- daniel-cussen 19y agoSuch a clever hack.
- staunch 19y agoFoggy memory, but either the CIA or KGB embedded tiny prisms in embassy window(s) so it was easy to capture the reflection. Without the prism it seems like this would be a real pain. Here's another awesome way to pick up sound covertly: http://www.nsa.gov/museum/museu00029.cfm http://www.nsa.gov/museum/museu00029.cfm I'd love to see some instructions how to do that easily. I'd love to try it.
