Professor Daisuke Koyama (Department of Electrical Engineering, Faculty of Science and Engineering), et al. developed a 1.5mm smartphone camera lens. With this lens, focal length can be freely adjusted using ultrasonic waves and liquid crystals, eliminating the need for moving parts. Therefore, this technology is expected to enable the design of even thinner smartphones in the near future.
The development of this lens was introduced in the Nikkei (newspaper) on June 4, 2018.
Further information can be found in the journal Applied Physics Letters.
