Utilising a hair-thin multimode optical fibre, the holographic endoscope allows minimally invasive, high-resolution in-vivo imaging at subcellular levels across any brain structure. The NEUROGATE project will significantly enhance the potential of this breakthrough technology for biomedical imaging by commercialising critical innovations in holographic endoscopy, developed through the prior ERC-PoC projects WOKEGATE and StrokeGATE.
