Abstract
Example embodiments include a dynamic wavefront sensor, a controllable wavefront offsetting element and a controller that controls the controllable wavefront offsetting element to offset selected non-plane wave aberration components in order to allow remaining non-plane wave aberration components to be more efficiently detected and measured.
Claims15
An apparatus comprising:
- a dynamic wavefront sensor configured to receive a wavefront and to output position values indicating the position of focused subwavefronts, with the wavefront comprising a plurality of subwavefronts, and with the wavefront including non-plane wave aberration components;
- a controllable wavefront offsetting element positioned to intercept the wavefront before it is incident on the wavefront sensor;
- and
- a controller, coupled to the controllable wavefront offsetting element, configured to control the controllable wavefront offsetting element to only offset selected non-plane wave aberration components of the wavefront in order to allow remaining non-plane wave aberration components of the wavefront to be more efficiently detected.

An apparatus comprising:
- a sub-wavefront focusing lens configured to focus a sub-wavefront, being a portion of a wavefront generated by a light source, to an image spot located on a focal plane, and with the wavefront including non-plane wave aberration components;
- a sequential wavefront scanning device configured to sequentially project different portions of an incident wavefront on the sub-wavefront focusing lens;
- a variable aperture configured to control the size of the sub-wavefront;
- a position sensing device, located substantially at the focal plane of the sub-wavefront focusing lens, configured to indicate the location of the image spot on the position sensing device;
- a controllable wavefront offsetting element positioned to intercept the wavefront before it is incident on the wavefront sensor;
- and
- a controller, coupled to the controllable wavefront offsetting element, configured to control the controllable wavefront offsetting element to only offset selected non-plane wave aberration components of the wavefront in order to allow remaining non-plane wave aberration components of the wavefront to be more efficiently detected.
