文摘
- •
Three practical retrace error correction methods are compared with simulation and experiments.
- •
Dynamic range of the three methods are sought out.
- •
Applicable conditions of the three methods are recommended.
- •
Aspherical reference wavefront enlarges the dynamic range of non-null aspheric testing.
- •
Scale of the tested figure error affects the accuracy and time consumption.
