86.201 用于照相制版的激光读、写系统——R.E.Amtower,美国专利,No.4393411,1983年7月12日公布。把物体象写入表面的系统包括:一个产生读数光束扫描物体,写入光束扫描相应的写入表面的光束装置;用来改变写入光束强度的调制器;使读数光束和调制写入光束合成的光束合成器,通常该读数光束和写入光束沿共同的光路都有微小的发散度;当读数光束扫描物体时,接收物体能量的装置;以及改变写入光束强度属写入表面上成象的装
86.201 Laser Reading and Writing System for Photographic Printing - R.E. Mettower, U.S. Patent No. 4,393,411, issued July 12, A system for writing an object image on a surface includes a beam generating means for generating a reading beam scanning object, a writing beam scanning the corresponding writing surface, a modulator for varying the intensity of the writing beam, and a combination of the reading beam and the modulation writing beam Of beam combiners generally having a slight divergence along a common optical path with the reading beam and the writing beam; means for receiving the energy of an object as the reading beam scans the object; and means for varying the intensity of the writing beam to image onto the writing surface The equipment
