摘要
A phase stepping common path radial shearing interferometer used for the measurement of wavefronts from white light sources is described. This has been implemented using the four-step phase stepping technique, which is usually used for laser wavefront measurement. The system is able to measure phase distributions with a peak-to-peak error of 0.3 radians.
