摘要

Abstract: Interferometers are used for routinely testing optical components and in engineering for the measurement of mechanical and thermal behavior of materials and components. Conventionally, for the most accurate measurements these interferometer systems are constructed from high-quality optical elements and include fine controls for precise alignment. In this new approach, all the errors of a poor quality, misaligned system are accepted then eliminated by a simple digital subtraction process. The method offers the possibility of devising very large aperture optical systems for traditional and engineering interferometers from inexpensive and basic components.!8
