1. An augmented reality optical system comprising:
a pulsed light emitting display generating a first light stream when in an on state;
a second light stream incoming from a real world environment;
one or more active beam splitters capable of transitioning from an active state to a non-active state and the one or more active beam splitters operative to both reflect the first light stream and allow the second light stream to pass through the one or more active beam splitters;
a processor; and
a storage having encoded thereon executable instructions that, when executed by the processor, cause the processor to carry out synchronizing on states of the pulsed light emitting display and active states of the one or more active beam splitters, such that when the pulsed light emitting display is in the on state the one or more active beam splitters transition to the active state, and when the pulsed light emitting display is in the off state the one or more active beam splitters transition to the non-active state;
wherein the one or more active beam splitters in the active state reflect the first light stream towards an eye of a user to show at least part of a virtual image; and
wherein the one or more active beam splitters in the non-active state allow the second light stream to pass through the one or more active beam splitters and towards the eye of the user.
