Abstract: In an embodiment, multiple conjugate planes are used to create a plurality of optical pupil planes and a plurality of image planes. These optical planes solve multiple problems and introduce significant performance enhancements in the system. In one implementation of a disclosed embodiment, the measurement channel is based on the reverse Shack-Hartmann principle. By introducing a relay system (for example a 4-f lens system) the slit plane could be made conjugate to the measured system pupil plane (unlike a previous implementation where the slits were places away from the pupil plane as it was not accessible directly). Creating a virtual pupil plane allows for more accurate placement of the plane without the need for contact with the measured optical system.

Abstract: A target surface in an eye is located using a dual aiming beam apparatus that transmits a first aiming beam of light and a second aiming beam of light. An optics subsystem receives a laser beam from a laser source, the first aiming beam of light, and the second aiming beam of light, and directs the beams of light to be incident with the target surface and aligns the beams of light such that they intersect at a point corresponding to a focus of the laser beam. An imaging apparatus captures an image of the target surface including a first spot corresponding to the first aiming beam of light and a second spot corresponding to a second aiming beam of light. A separation between the spots indicates that the focus is away from the target surface, while overlapping spots indicate the focus is at or on the target surface.
