The Laserspy apparatus makes it possible to eavesdrop over long distances.
A laser beam is aimed at a window pane. The laser is reflected by the plate of glass and received by a light-sensitive cell positioned far away. This makes it possible to listen in on the conversation taking place behind the window.
The laser registers the vibrations that the sounds spoken within the room impart to the pane of glass, and the light pulse of the reflected laser conveys this information over long distances. The laser is thus the transmitter and receiver of the light code that, after it’s reflected, is the carrier of the verbalized information. Chrystal is capable of decoding the reflected light.
