Abstract
The invention discloses a design method of an elliptical optical attenuation piece. The elliptical optical attenuation piece structurally comprises a plurality of adjacent ellipses, wherein the proportion of the long axis and the short axis of each ellipse is the same, but the special values of the long axis and the short axis are different and can be adjusted according to actual conditions. The method includes the steps of firstly, using Photoshop 6.0 to design the structural parameters of the elliptical optical attenuation piece and make a boundary on the outermost side; secondly using CorelDrawX5 to copy the designed elliptical optical attenuation piece to the newly-built file of the CorelDrawX5 so as to change the designed elliptical optical attenuation piece into a vector diagram, and adjusting the size of the vector diagram according to actual conditions to allow the size of the vector diagram to be matched with the size of a film; thirdly, using a Propalette 8000 film output device to output the elliptical optical attenuation piece; fourthly, completing. The method has the advantages that by the elliptical optical attenuation piece designed by the method, an original signal can be kept in an undistorted manner, and smooth attenuation can be realized; elliptical optical attenuation piece is flexible in design, simple to manufacture and good in repeatability; a good foundation for widening the application of the elliptical optical attenuation piece to other special fields is laid.
