A double-sided, auto-register, non-artwork projection expose system for use in the production of printed circuit boards and cards is described. The fast automated projection system (FAPS) includes the following functional components which are described in detail later on: 1. Optics head 2, shown in Fig. 1, which contains the Liquid Crystal Light Valve (LCLV) light source and optics, 2. Auto registration system, shown in Fig. 2, which contains quadrant detectors positioner, servo motors, and logic, (Image Omitted) 3. Data handler which contains two controllers for the optics head, a main data handling unit, and the interface to the host computer (if required), shown in Fig. 3, and 4. A material handler for the load/unload operation.
