The Zygo interference Pattern Processor was designed to evaluate either hard copy interferograms or real time interference patterns rapidly and accurately. Since its introduction one year ago, it has undergone an evolution leading t two new systems which shall be described here. In addition, continuing software development has led to a highly flexible operating system, satisfying many users requirements. These new features have been stimulated in the course of their development by various use requirements leading to the refinement and definition of the new systems. For those interested only in the basic analysis of an interference pattern, a minimum system has been designed and built. Those requiring not only the entire analysis capability but multiple systems can now time share one processor. Continuing developments for the reduction of very complex fringe patterns will on offer the industry a tool for measuring virtually all of its interference pattern's., Before providing more details of the nature of these new systems, a brief description of the basic system and its operation will be given first.
