Optical system for a retinal scan display and method for projecting image contents onto a retina

An optical system for a virtual retinal display, comprising:

• an image source which provides image content in the form of image data;
• an image processing device for the image data;
• a projector unit with a time-modulable light source configured to generate at least one light beam, and with a drivable deflection device for the at least one light beam for scanning projection of the image content;
• a first deflection unit onto which the image content is projectable and which is configured to direct the projected image content onto a user's eye;
• a second deflection unit, arranged between the projector unit and the first deflection unit, which is configured to deflect the entire light beam via a first imaging path at a first point in time and via a second imaging path at a second point in time subsequent to the first point in time onto at least one projection region of the first deflection unit;
• and
• an optical replication component arranged in the at least one projection region of the first deflection unit and configured to direct the projected image content in replicated and spatially offset manner onto the user's eye, such that a plurality of exit pupils which are arranged spatially offset from one another and include the image content are generated.

A method for projecting image content onto a user's retina using an optical system including:

• an image source which provides image content in the form of image data,
• an image processing device for the image data,
• a projector unit with a time-modulable light source configured to generate at least one light beam and with a drivable deflection device for the at least one light beam for scanning projection of the image content,
• a first deflection unit onto which the image content is projected and which directs the projected image content onto a user's eye,
• a second deflection unit arranged between the projector unit and first deflection unit, and
• an optical replication component which is arranged in a projection region of the first deflection unit,
• the method comprising:
• deflecting the entire light beam using the second deflection unit via a first imaging path at a first point in time and via a second imaging path at a second point in time subsequent to the first point in time onto the at least one projection region of the first deflection unit;
• and
• replicating the projected image content using the optical replication component and directing the replicated image content in spatially offset manner onto the user's eye, such that a plurality of exit pupils which are arranged spatially offset from one another and include the image content are generated.
