Two camera off-axis eye tracker |
| abstract |
Improved laser eye surgery and/or eye tracking systems, methods, and devices make use of two image capture devices (13), generally with both image capture devices disposed off the optical axis of the eye and/or any laser delivery system (28). This provides an enhanced imaging contrast for an imaging capture device such as a camera with a charge-couple device (CCD), particularly when using infrared imaging to track a pupil of the eye. The two off-axis cameras may be used independently to track movements of the pupil along two orthogonal lateral axes of the eye (often called X-Y tracking), and may also indicate a position of the eye along the optical or Z axis. |
