Retinal projection with a narrow beam offers a broad depth of field. However, it has a limited range of permissible eye positions for optimal viewing (eyebox). In this paper, we developed an optical system that comprises a light deflection unit, which sequentially arranges the light beam to the eye, and then a light scanning unit for rendering the image. The developed optical system can achieve a wide eyebox while suppressing aberrations.
