Abstract
Methods and systems for using narrow band angular filters or reflectors to reflect or filter out satellite diffraction orders for manufacturing of target optical components to propagate target diffraction orders into a waveguide are provided. The system may include a light source for directing light into a liquid crystal polarization hologram (LCPH) optical element. The optical system may include at least one LCPH optical element that polarizes light and a narrow band angular filter or reflector. The LCPH may receive one or more rays of light associated with the light from a light source and may diffract the rays of light. The rays of light may be directed to a narrow band angular filter or reflector to filter or reflect satellite diffraction orders and allow target diffraction orders to be transmitted on a final sample or target component (e.g., display of a HMD, or any augmented reality device).
