Sonar Light Pulse

Submarines are able to navigate because of SONAR (Sound Navigation and Raging) techniques. Submarines emit pulses of sound waves that travel through the water, reflect objects in the environment and return to the ship. Because the speed of sound in water is known, the distance between the submarine and the object can be calculated. Animals such as whales, dolphins and bats have been using the same principle to navigate for ages. This illustrates that animal studies can enrich our knowledge and offer inspiration for innovation.

SONAR Light Pulse is inspired by bats. Paul Cremers decided to use a light pulse instead of a sound pulse for his artwork, visualizing this echolocation system. How does it work? Call! And emit a light pulse through the underground metro passage at Waterlooplein.
