The Methods and Experiments of Shape Measurement for Off-Axis Conic Aspheric Surface

The off-axis conic aspheric surface is widely used as a component in modern optical systems. It is critical for this kind of surface to obtain the real accuracy of the shape during optical processing. As is widely known, the null test is an effective method to measure the shape accuracy with high pr...
