"Printing" on water using waves

By squirrelbait - July 24, 2006

Using Bessel functions, 50 water wave generators encircling a cylindrical tank 1.6 meters in diameter and 30 cm deep makes up the crazy device that moves up and down in controlled motions producing a number of cylindrical waves that act as pixels. The device, developed by Researchers at Akishima Laboratories (Mitsui Zosen)in conjunction with professor Shigeru Naito of Osaka University, can draw each letter of the roman alphabet as well as a few basic kanji letters. Although each letter or drawing only lasts for a moment, it can be recreated every 3 seconds.
