Paper Abstract

The impact of tilt bias errors in multiple wavefront interferometry is assessed in terms of its effect on the ability to determine piston phase differences between wavefronts from such interferometry. The error in such piston phase determination due to tilt bias has been found to be substantial. On the other hand, several techniques have been found to be viable in which both tilt and piston phase errors may be determined simultaneously from such interferometry with proper algorithms.
