". In more recent versions, the headpiece includes a miniaturized objective lens for optical coupling, relaying the light to and from the optical fiber" as it was 26 years ago. To collect some light from highly scattered medium FFS...

And... 5 years later... ".., the idea of using fiber optics for miniaturized neuroimaging devices was implemented and extended to other imaging modalities (Engelbrecht et al., 2008; Liu et al., 2013)."

"In a fiber optic-adapted system, an optical-fiber bundle is employed to transmit the illumination and detected light signals (either fluorescence or reflectance) to and from a conventional bench-top microscopy system. In early versions of this approach, the optical fibers were in direct contact with the brain tissue without the use of any lens (Ferezou et al., 2006)." Bullshit
