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 to compensate for projection errors when outputting images using a smart-glasses system. At least one image is produced using an arithmetic logic unit of the system. The image produced or an image to be output is transmitted by the arithmetic logic unit to a micro-electromechanical output unit, particularly smart glasses, of the system. Before the image is output by the output unit, a correction algorithm is executed to generate a corrected image to be output. Image regions of the corrected image to be output are assigned at least one stored position within the produced image via at least one stored transformation function depending in each case on a position within the corrected image to be output. At least one image-region parameter is ascertained for the image regions to be generated depending in each case on the stored position assigned to the respective image region to be generated.
