Abstract
A concept for near real-time automatic processing of interferometric data from a Laser Unequal Path Interferometer (LUPI) using an EO camera and mini-computer is presented. A major advantage of this system is a straightforward replacement of the standard film camera by an EO camera (with no further modification required to the interferometer). Testing of the optical systems with obstructions and/or spiders and baffles within the aperture is done automatically. The system is designed for implementation in the fabrication/test cycle of ultra-high quality optical components and systems; where averaging is used to reduce random test errors (e.g., vibration and air turbulence). The system is configured as having portable E/O cameras and monitors hooked into ports at various lab facilities via cabling to the mini-computer at the Data Reduction Station. Itek's Optics Package Fringe Reduction (FRED) software is available at the Data Reduction Station for full analysis capability.
