Abstract
A method for a pupil detection and/or pupil tracking with the aid of an evaluation of a speckle pattern back-reflected by an eye of a light of an infrared laser irradiated into the eye. At least the light of the infrared laser irradiated into the eye is scanned via a holographic optical element that includes different refractive structures, the different refractive structures being configured in such a way that they each generate a different visual defect correction.
