Most projectors create an image by shining a light through a small transparent lens, but some newer types of projectors can project the image directly, by using lasers. A virtual retinal display, or retinal projector, is a projector that projects an image directly on the retina instead of using an external projection screen. =Challenges= =Approaches= YfvTjQ9MCwY =References= * [[https://en.wikipedia.org/wiki/Projector|Wikipedia: Projector]]
