Transmit sound and other types of signals – via a laser. First, connect various inputs to the laser/transmitter module – such as a microphone, radio, or a computer sound card or CD-ROM drive. Then, aim the modulated laser beam at the sensor panel of the receiver module. The built-in speaker plays the audio loud and clear, even over a great distance!
Conduct exciting experiments with sound transmission, bouncing the laser off mirrors, through glass and translucent mediums, and over varying distances.
- Receiver module has an output that can be connected to an oscilloscope for analysis or to an amplified speaker system.
- Both the transmitter and receiver modules operate on 9 V batteries as well as AC adapters (two adapters are included).
Radio not included.
