摘要：
An improved method for generating masters having a plurality of randomly distributed speckle suitable for making seamless light shaping diffusers of virtually any size and at low cost is disclosed herein. The method utilizes incoherent light to record a desired speckle pattern in a photosensitive medium which is then exposed in an imagesetter.
