Abstract
Augmented reality glasses can include a first laser, a second laser, and a scanning mirror. The augmented reality glasses can also include a first polarization selective reflector and a second polarization selective reflector. The first polarization selective reflector is arranged to receive light from the first laser and reflect light received from the first laser at a first angle to the scanning mirror, and the second polarization selective reflector is arranged to receive light from the second laser and reflect light received from the second laser at a second angle to the scanning mirror. The augmented reality glasses can also have an eyepiece having an input coupling port arranged to receive light reflected by the scanning mirror.
