Abstract
Here, we present triple sets of wavefront modulation by proposing quarter‐waveplate‐based GPL (QWP GPL). We demonstrate nine depth‐switchable AR imaging functions with a bi‐stack condition of the QWP GPL modules. The presented QWP‐based GPL module scheme is advantageous for increasing depth‐switchable layers without increasing the switchable optic units required. In addition, the AR display optics based on the QWP GPL module can further improve form‐factor issues and AR imaging properties.
