38‐1: Transverse Chromatic Aberrations in Virtual Reality Devices

Abstract

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 Oculus Go VR HMD. Results show a measurable TCA for angles larger than approximately 5 o from the center of the field of view.

P‐49: Angular Dependent Point Spread Function Analysis for Virtual Reality Head Mounted Displays

“…One challenge with a 2D PSF and 2D MTF across the FOV, is identifying the best metric to representing the data. A common metric for representing PSF is the Strehl ratio [8]. The Strehl ratio can be calculated by normalizing the PSF by its area and then dividing the PSF amplitude by the diffraction limited PSF amplitude.…”
