Abstract

In imaging system (), a spatial light modulator () is configured to produce images () by scanning a plurality light beams (). A first optical element () is configured to cause the plurality of light beams to converge along an optical path () defined between the first optical element and the spatial light modulator. A second optical element () is disposed between the spatial light modulator and a waveguide (). The first optical element and the spatial light modulator are arranged such that an image plane () is created between the spatial light modulator and the second optical element. The second optical element is configured to collect the diverging light () from the image plane and collimate it. The second optical element then delivers the collimated light to a pupil () at an input of the waveguide.
