发明名称 Method for determining aperture shape
摘要 A mathematical method for selecting the shape for an occluding aperture which is to be positioned at a predetermined aperture location in a light path extending between an illuminated line object and a linear photosensor array. Through use of the aperture selected according to the method, a light intensity measurement is obtained across the linear photosensor array which is uniformly proportional to the light intensity across the illuminated line object.
