Abstract

Abstract : The measurement of eyebox size is important in the design, manufacturing, and user experience of AR/VR near‐eye display (NED) devices. Previous studies have focused on characterization of luminance and the brightness‐defined eyebox. We propose to use modulation transfer function (MTF) to define contrast‐based eyebox, measured with the rectangular line‐pair chart at varying spatial frequencies. We find it is important to examine both brightness‐based eyebox and MTF contrast‐based eyebox to decide the limiting factor, which depends on the specific NED design and the displayed content.
