More Information
Summary:A binocular head mounted display includes a frame, right and left displays, an alignment sensor, and a control system. The right and left displays display right and left images to a user and are mounted to the frame. The alignment sensor includes a first laser source mounted proximate to one of the right or left displays and a first photo-detector array mounted opposite the first laser source and proximate to an opposite one of the right or left displays. The first alignment sensor is mounted to measure misalignment between the right and left displays due to deformation of the frame about one or more rotational axes and to generate a signal that is indicative of the misalignment. The control system is coupled to the alignment sensor to receive the signal and to calculate the misalignment based at least in part upon the signal.
