Opis
Bada widzenie dwufotonowe, czyli zjawisko percepcji impulsowych laserów bliskiej podczerwieni dzięki dwufotonowej absorpcji w pigmentach wzrokowych. Skupia się na opracowaniu układów optycznych i metod psychofizycznego testowania tego nowo odkrytego sposobu percepcji światła oraz na integracji tych metod z okulistycznymi systemami obrazowania.
Ostatnio w ICTER realizuje projekt Proof of Concept Fundacji na Rzecz Nauki Polskiej, którego celem jest skonstruowanie prototypu dwufotonowych okularów AR.

Zespół Obrazowania Optycznego
Koncentrujemy się na rozwoju technik obrazowania i wykorzystaniu ich w wielu układach biologicznych i chemicznych. Unikalność naszego podejścia polega na wykorzystaniu nie tylko amplitudy światła, ale również jego fazy w celu opracowania nowych, najwyższej klasy systemów obrazowania.
