The integration of an adjustable-dynamic zoom lens in a thin cellphone, in a miniaturized microscope, or at the remote end of a medical endoscope requires complex lenses that can handle the full optical spectrum and be reshaped electrically within milliseconds.
To meet this challenge, scientists from the Institut de la Vision teamed up with a group from the Institute of Photonic Sciences (ICFO) to develop a dynamically tunable lens that, according to the scientists, is capable of achieving almost any complex optical function. The lens, called Smartlens, is able to manipulate light without any mechanical movement. The Smarlens design is based on a method of deterministic phase-front shaping using a planar thermo-optical module and…READ MORE
