Remarkable concept where you listen to sounds picked up from a reflecting surface illuminated by a laser. These light reflections, or scatter, are reproduced back to the original sound by our special optical receiver.
Assembled laser and receiver modules may be placed on video tripods and temporarily aligned for limited performance demonstration systems. They may also be enclosed as shown in the instructions for use as a field worthy device with a potential range of up to 500 feet. May be used as a long range laser voice communicator with a range usable to 10 miles line of sight. Low cost audio surveillance science project or useful device for listening to power line faults, over pressured pipes, etc.
The modules can be set up on individual tripods to show the proof of concept. This is not a field-worthy system for covert surveillance. To build a usable field-worthy system is up to the purchaser of the modules to enclose them in a housing and place them on a stable platform that he must build himself. He then must select the optics needed for his application. This may be beyond the capabilities of many buyers of these modules, so it is strongly suggested to purchase the downloadable or paper plans and study them to get an idea of what is involved.
