An optical system for a virtual retinal scan display. The optical system includes an image source which supplies image data, an image processing device for the image data, a projector unit having a light source modulatable in time for generating a light beam, and an actuable refraction device for the light beam for the scanning projection of the image content, a deflection unit onto which the image content is able to be projected and which is designed to guide the projected image content onto an eye of a user, and an adaptive optical element for modifying a beam divergence, which is situated in the optical path between the light source and the deflection unit. The adaptive optical element is able to be actuated so that the beam divergence of the light beam is variable as a function of the angle of incidence of the light beam on the deflection unit.

Optical system for a virtual retinal scan display, and method for projecting image content onto a retina

A method for activating a drive unit of a deflection unit of a two-dimensional microscanner device. First and second control signals for activating the drive unit of the deflection unit are initially generated using a processing unit. The first and second control signals are subsequently transferred to the drive unit. A sinusoidal first movement of the deflection unit about a first axis and a sinusoidal second movement of the deflection unit about a second axis are carried out at a first point in time based on the transferred control signals. The first control signals are then adapted so that a periodic third movement is superimposed on the first movement at a second point in time following the first point in time. Alternatively, the second control signals are adapted so that a periodic fourth movement is superimposed on the second movement at the second point in time following the first.
