摘要:
An optical assembly includes a beam steering device and a holographic optical element. The beam steering device is switchable between different states including a first state and a second state. The beam steering device includes a first polarization-selective optical element and a first tunable optical retarder optically coupled with the first polarization-selective optical element. The holographic optical element is positioned relative to the beam steering device for receiving light from the beam steering device and projecting a first light pattern while the beam steering device is in the first state and a second light pattern distinct from the first light pattern while the beam steering device is in the second state.
