The invention relates to a method for pupil detection and/or pupil tracking by means of an evaluation of a spot pattern of light of an infrared laser (12) incident into an eye (10) reflected back by the eye (10). According to the invention, at least the light emitted by the infrared laser (12) into the eye (10) is scanned through a holographic optical element (HOE, 18) which comprises different refractive structures (14, 16), the different refractive structures (14, 16) being designed such that the different refractive structures each produce different visual defect corrections. 本发明从一种用于借助对红外激光器(12)的射入到眼睛(10)中的光的通过眼睛(10)反射回来的斑点图案的分析处理进行瞳孔探测和/或瞳孔跟踪的方法出发。提出，至少所述红外激光器(12)的射入到所述眼睛(10)中的光扫描经过全息光学元件(HOE，18)，所述全息光学元件包括不同的折射结构(14，16)，其中，所述不同的折射结构(14，16)如此构造，使得所述不同的折射结构分别产生不同的视觉缺陷校正。
