Abstract
As part of an examination device, an input or output optical coupler device for transmitting photons between an optical source or detector and an examined body part includes an array of optical fibers with end portions freely protruding as cantilevers from a support. The optical fibers have the end portions fabricated, sized and distributed to penetrate freely extending hair when the support is placed on the head or other surface of a subject to make optical contact directly over an array of points with the surface of the scalp or skin below the free hair.
