3‐4: Human Perception as a Measure: Evaluating Waveguide Non‐Uniformity in Augmented Reality Technology

With the rapid development of optical waveguide technology, an essential component for creating compact and efficient AR devices, its application in the field of augmented reality (AR) is becoming more and more widespread. When paired with a variety of microdisplay technologies (LCoS, DLP, Micro‐LED), it enables the production of high‐performance AR products. In order to achieve a deeper immersive experience, designs such as large‐angle light‐emitting microdisplay technology and dilated pupil gratings are often used to provide a wider field of view and a larger eyebox (the viewing area where the eye can see the entire image). However, these designs pose challenges because they can exacerbate brightness and color inhomogeneity, disrupting the user's experience. We address this shortcoming by proposing an evaluation model based on the human visual system, which introduces a new method for constructing frequency‐domain filters in a uniform color space and simulates the processing of early human vision , thereby providing a more accurate reflection of human eye perception and a more realistic evaluation of AR display performance. By offering valuable insights and guidance, our model effectively enhances the quality of AR displays, positioning it as an indispensable tool for researchers, engineers, and industry professionals.
