Quartz-Blazed Grating Applied on Autostereoscopic Display

By applying reactive ion etching (RIE) to a blazed grating on quartz substrates, the grating can be utilized as a splitter in autostereoscopic displays. Furthermore, a solution for the pattern alignment on transparent substrates is also proposed. By measuring the diffraction efficiency and crosstalk between the left and right fields of view (FOV), the capability of the element to deliver stereoscopic images is demonstrated.
