Whales are orientating according to ultrasonic waves – with the principle that the time lag between the emitted sound waves and their reflection is linearly proportional to the object between the emitter and he receptor.
This relationship can also be observed at the echo-effect. The larger the distance between the sound-emitter and the reflecting surface, the more time it takes to for the voice to be heard.
If we put a light source near a camera lens, we can observe a similar phenomenon. Objects closer to us appear lighter, whereas objects further away darken in proportion to the distance. If we reverse this process, we can obtain the surface of a 3D image. This program also applies this principle by using the Night-shoot mode of the camera. The result is a 3-D surface exposed to the original video signal is projection - the picture becomes relatable and observable from different angles.
