Abstract
An image relay device that projects laser light representing an image emitted from a projection device onto the retina is provided. The image relay device includes a projection device, a first optical member, and a second optical member. The projection device includes a light source configured to emit laser light and a scan unit configured to scan the laser light based on image data. The first optical member receives an image light from the projection device and converts the image light which is a parallel light, to light beams of convergent light. The second optical member converts the light beams output from the first optical member into parallel light.
