We demonstrate a method for measuring the transverse chromatic aberration (TCA) in a virtual reality head-mounted display (VR HMD). This procedure was used to characterize the optical performance of the Oculus Go VR HMD. Results show a measurable TCA for angles larger than approximately 6◦ from the center of the field of view. TCA can be thought of as a wavelength dependent magnification, and as a result, the relative size of objects vary based on the rendering color. In addition, this leads to color changes in the image due to mixing with neighboring pixels, which impacts image quality. The test results for the Oculus Go show promise for characterizing TCA across different HMDs.
我们展示了一种在虚拟现实头戴式显示器(VR HMD)中测量横向色差(TCA)的方法。该程序用于表征Oculus Go VR HMD的光学性能。结果显示一个可测量的角度大于约6◦从视野中心的TCA。TCA可以被认为是波长相关的放大倍率，因此，物体的相对大小根据渲染颜色而变化。此外，这还会导致图像因与相邻像素混合而发生颜色变化，从而影响图像质量。Oculus Go的测试结果显示，它有望在不同的头戴设备上表征TCA。
