The method including: emitting laser light; providing a high-frequency signal during the emission of the laser light, a modulation frequency of the high-frequency signal being between 10-500 MHz; detecting an optical response by the light detector in reaction to the emitted laser light while providing the high-frequency signal, which is arranged such that a detection signal caused by a macroscopic object positioned between a first and second distance is reduced in comparison to a detection signal caused by the macroscopic object at the same position without providing the high-frequency signal.

Abstract: A method for projecting image contents onto a user's retina using an optical system. A light beam is first projected onto a diverting unit of the optical system using a projector unit of the optical system. The light beam is subsequently diverted to the position of the user's eye.

Second image data are generated using an image-processing device based on the stored and ascertained deviation of the actual state of the projected light beam from the desired state. The second image data are received using the projector unit. The received second image data are projected at successive second time intervals using the projector unit. At least two of the second time intervals differ from one another in terms of time.
