| Abstract: | On the basis of defocus and non-coaxality induced by framing lenses in an approximate circle, the precision formulae for calculating the defoous of image points in the film in another approximate circle have been deduced in this paper. Errors caused by the traditional calculating method have been eliminated and more reliable data can been obtained for the evaluation of the image quality in a rotating mirror framing camera. |
