Digital Fringe Analysis with

Quick Fringe





Quick Fringe is used to extract quantitative wavefront accuracy measurements from a laser interferogram. Interfacing with optical interferometers via a video camera and frame grabber, Quick Fringe produces accurate test reports with a minimum of effort.

Renowned for its ease of use, Quick Fringe has been used for applications ranging from telescope manufacturing to cross-checking Hubble Space Telescope instrumentation.

Key Benefits:
  • Automatic fringe tracing with manual edit option
  • Quick and accurate analysis
  • User-configurable printed test reports
  • Interfaces directly to frame grabber cards

This demo program is intended to demonstrate how Quick Fringe is used to analyze interferograms. There are several limitations to the demo:

  • It can only read the included sample files
  • Frame grabber support is not included
  • It cannot save files

We recommend that you review the on-line help before using the package. For your convenience, the demo will launch the on-line help automatically when you start the program.
