Abstract
An optical system includes a light guide member having an incident surface, a first surface and a light emergent surface; and at least one prism provided on the first surface and configured to reflect light received by the incident surface and travelling inside the light guide member, towards the light emergent surface. The light guide member provides an optical path along which the light that has entered through the incident surface is directly reflected from the prism and allowed to emerge from the light emergent surface. The light guide member also provides another optical path along which the light that has entered through the incident surface is once reflected from the second surface, reflected again from the prism, and then allowed to emerge from the light emergent surface. The optical system is configured to be coupled to a light source, to illuminate a display system which projects a virtual image onto a target space.
