Description
Exploration of two-photon vision, i.e., a phenomenon of perception of pulsed near-infrared lasers due to two-photon absorption in visual pigments. Focuses on developing optical systems and methods for psychophysical testing of this newly discovered way of perception of light and on integrating these methods into ophthalmic imaging systems.
Recently, at ICTER, she has been implementing the Proof of Concept project of the Foundation for Polish Science, which aims to construct a prototype of two-photon AR glasses.
