Abstract
An optical profiling system characterizes distortion of a head-mounted display (HMD) under test. The optical profiling system includes a camera assembly and a controller. The controller provides presenting instructions that cause the HMD under test to present test patterns and also provides imaging instructions that cause the camera assembly to capture images of the test patterns presented by the HMD under test. The camera assembly includes one or more characterization cameras. A characterization camera is configured to mimic movement of a human eye and is positioned in an eye box region of the HMD under test. Using the images captured by the camera assembly, the controller measures distortion of the HMD under test. The controller may generate a report charactering the HMD under test based on the measured distortion.
