Miniaturized optical head approach, particularly for endoscope.

摘要

optical head miniaturized intended for equipping the distal end of a bundle of flexible optical fibers (2), said optical head intended to come into contact with a surface analysis and optical means (3) comprising focusing an excitation signal being leaves said bundle of fibers at a focal point called excitation located at a given subsurface analysis and to extract a retroemitida signal by the focal point excitation is conducted return by said fiber bundle depth, comprising a tube optics carrier (4) of circular section within which are introduced by a side portion remote terminal (1) of the fiber bundle (2) and on the other the optical means, the latter a blade (21) comprising arranged in contact with the end (14) of the fiber bundle whose index is close to the core of the fibers and a focussing optical block (3), one output window (30) in addition ost encontacto intended to come with the analyzing surface and adapted to perform rate matching so that release of parasitic reflection occurring on the analyzing surface.
