    Abstract: A scanning laser ophthalmoscope may include: a light source configured to emit laser light; a scanner configured to scan the laser light emitted from the light source two-dimensionally; a guide mirror configured to guide the laser light scanned by the scanner to a fundus of an eye of a subject; a guide mirror holder configured to hold the guide mirror in a predetermined positional relationship with the eye of the subject; a light receiver configured to receive reflected light of the laser light reflected on the fundus; and an image generator configured to generate a fundus image based on the reflected light received by the light receiver. The guide mirror may be disposed on a path connecting the scanner and the fundus of the eye of the subject, and disposed in front of the eye of the subject. The scanner may be disposed at the guide mirror holder.

    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.
