Abstract : The present invention relates to an optical system for viewing a full 360 annular area on the inside of a cavity. The inspector can by simple longitudinal motion of the viewing instrument, relative to the cavity, rapidly inspect the interior surface without rotating the part being inspected. The design of the present device permits a brilliant light source to be used to illuminate either a broad or narrow band of wall surface. One of the objects of this invention is to provide an optical system for inspecting the interior of an artillery projectile.
