Decades ago I read about an eavesdropping rig that bounced a laser off a window and could detect the variations in the reflected beams to capture every spoken word inside the room. Curtains, blinds and such did not stop the glass from acting as a speaker diaphragm. Its only distance limit was the spread of the laser beam- the beam spot on the glass had to be some percentage smaller than the sheet of glass you were aiming it at.

[@christopherpardell4418]

@@expertoflizardcorrugation3967 I don’t know a lot about this- but my understanding of how laser ranging works is that a frosted window would scatter the light, which would only make it easier to pick up the unique wavelength in more than one location. For example, soldiers using a laser target designator fire a laser at something they want a bomb to hit… the laser light reflects off in all sorts of directions, and the sensor on the bomb can detect this light and home in on the object reflecting the light. Because the laser light is a coherent beam from the designator- the bomb can’t see that beam and so won’t steer towards the soldiers, but it Can see the light that is scattered off of the object because it has been scattered off in all directions. The bomb can see the laser light bouncing off the object from anywhere. Similarly, a laser eavesdropper would simply be looking for the interference pattern in the reflected light versus the initial beam to detect how the window pane is vibrating from sound inside the room. I would think the best way to interdict such a system would be to coat the windows in something like Fanta Black that absorbs ALL light that hots it… but then, it wouldn’t be much of a window, would it?

Very interesting video. Sure, the sound signal is subject to Nyquist sampling constraints. Each observation from the image is effectively the output from a planar microphone. Consider taking observations from >1 spot from the images. Observing multiple vibrations of the planar microphone across the surfaces will effectively multiply the sampling frequency by the number of observations. The wave pressure will be smeared in time across the image at the speed of sound. It might be possible to reconstruct some directional information as well by noting the progress of the wavefronts across the scene. Microphones arranged across multiple planes (e.g. x-y, y-z, x-z), will observe different signals. It might be possible to improve direction-finding accuracy by modulating the orientation of the planar microphones (like a dog cocking its ears). Since you know the medium (sound in air at some temperature), you are also getting information about how observed signals vary over time..

Maybe you could use the rolling shutter effect to get more "frames" per second? Not every pixel of a frame gets recorded at the same time, so if you know what the order is, you might be able to use that additional information. There was a case in Italy (?) where some suspects that were hiding uploaded a video of themselves in a room and the Police was able to find out in wich area it was taken. The power grid regularly sends some information by modulating the voltage, wich briefly creates some flicker in the lamps. Thanks to the rolling shutter of the camera they were able to decode that information and find out to which part of the powergrid the hous was connected to. (sorry, it's pretty hard to explain, I'm not that good in english)
