Abstract:
A discrete wavefront measurement device uses a variable transmission filter (VTF) to decouple the dynamic range of tilt angle measurements in the wavefront from the spatial sampling resolution and the measurement sensitivity as regards the physics of the readout. This approach allows the discrete wavefront measurement device to be configured to a specified dynamic range, transverse sampling resolution and measurement sensitivity at low cost.
