Abstract
A laser scanning projection system for use in illuminating a waveguide of an augmented reality or virtual reality headset is disclosed. The laser scanning projection system comprises a laser source configured to emit light towards a pair of polarising beam splitters. The polarising beam splitters direct light onto a plurality of mirrors through a plurality of quarter waveplates. The laser scanning projection system further comprises a waveguide having an input configured to receive the light such that the exit pupil formed at the laser scanner is relayed into the waveguide.
