摘要
An optical assembly for an eye-tracking camera includes an aperture stop, a first optical surface, and a second optical surface. The optical assembly is configured to receive non-visible light reflected or scattered by an eye and to direct the non-visible light to an image sensor along an optical path, where the non-visible light is received from an optical combiner of an eye-tracking system. The first optical surface is disposed on the optical path and is configured to correct for field-independent optical aberrations induced by the optical combiner. The second optical surface is disposed on the optical path and is configured to correct for field-dependent optical aberrations induced by the optical combiner.
