OPTICAL PROJECTION DEVICE FOR DISPLAY MEANS SUCH AS AUGMENTED REALITY GLASSES

摘要

An optical projection device for a display such as augmented reality glasses. The optical system includes a planar optical guide; at least two input optics; at least two collimation elements, each being associated with an input optics, and directly located on a face of the planar optical guide; and conjugation device, arranged to conjugate in twos an input optics and the associated collimation element. The invention provides a wide field and compact offset projection device.
