Motion picture film projector illumination system for minimizing film buckle |
摘要 |
A motion picture film projector illumination system (100) for minimizing film buckle comprises a light source (405) for producing a beam of light (416). Beam shaping optics (411) focus the light beam onto a film through an aperture (408) having an aperture opening (410) corresponding to a film frame (324). A secondary beam steering optics (465) directs stray light around edges of the aperture to illuminate film edge to frame edge areas (446).
