A method for actuating an actuable deflection device of an optical system for a virtual retinal display. A first eye status of the user of the virtual retinal display, detected and/or determined using an eye status detection device of the optical system, is received by way of a control unit of the optical system at a first time. In addition, first actuation signals are generated for the actuable deflection device using the control unit, in such a way that the scanning region of the deflection device is adjusted in accordance with the detected and/or determined first eye status of the user.

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.

A method for a calibration of at least one laser diode, in particular at least one laser diode of a laser projection device. The at least one laser diode is calibrated on the basis of a comparison of at least one currently acquired characteristic value of the at least one laser diode with at least one characteristic value, stored in at least one database, of a model laser diode that is at least substantially identical in construction to the at least one laser diode.

A method for calibrating a projection device, the projection device being equipped with at least two controllable and regulatable light sources, which each transmit a beam component of a scanning beam. The calibration method includes defining a reference beam for the scanning beam; determining, in each instance, a dewarping function for the x-projector coordinate and for the y-projector coordinate of the reference beam, each dewarping function converting the specific projector coordinate to corresponding image coordinates, which are assigned to the image information; determining, in each instance, an offset function for the x-projector coordinate and the y-projector coordinate for all beam components, each offset function approximating the offset between the specific x- or y-image coordinate of the reference beam and the x- or y-image coordinate of the respective beam component.
