Abstract
A retinal projection device includes: a light source that emits laser light; a movable mirror that performs scanning with the laser light; and a reflector that projects an image onto a retina of a user wearing a near eye wearable device by reflecting the laser light having passed through the movable mirror and irradiating the retina with reflected light. The reflector includes a plurality of unit regions provided along a surface of a lens of the near eye wearable device, and the surface faces an eyeball of the user. Each of the plurality of unit regions is a nanostructure to reflect the laser light at a reflection angle corresponding to a position where the unit region is provided when the laser light having passed through the movable mirror is incident on the unit region.
