In every optical system, degradations in image quality result from wavefront error (aberrations in the shape of light, which prevent rays from converging at a single focal point).? JPL has developed and successfully demonstrated software that measures the wavefront error of the entire optical system at once, using only the imagery collected from a point source of light.? The Adaptive MGS Phase Retrieval software measures wavefront error with extremely high accuracy.? Not only does this allow computer controlled correction of the optics during testing and assembly, but provides for intelligent control of active optical components (such as deformable mirrors) to correct wavefront error in already-built optical systems.
