A Method for Determining the Shape of the Image Surface in 16-mm Projection

Sixteen-millimeter projection is becoming more and more professional in its application, and it is beginning to be judged by professional standards. One characteristic of 16-mm projection which needs improvement is the sharpness of the projected image. A method is presented for describing the shape of the focal surface; the departure of this surface from a plane explains a great deal of the lack of sharpness in the image. The contributions of the elements of the optical system and the design of the gate are discussed.
