The special-function large-angular neutral variable density disk is a new type of star simulator with large dynamical scale
which can simulate the intensity of weak star in the sky and demarcate the characteristics of the universal background.It has been applied to some very important fields.During our investi- gation
we have designed a special shutter system
which made the light density continoua]ly variable within the range of 0—330° on the substrate with the maxium of 274 times and minimum of 0.01.Its facility region is 0.4—1.1μm with better neutral density and the large nonlinearity distribution with the angular variation of the subrtrate.
