1. An augmented/extended reality (AXR) wearable display apparatus to be worn by a viewer, comprising:
a headset support frame;
one or more front facing cameras mounted to the headset support frame;
an eye-tracking system configured to provide a signal indicating a pupil position of the viewer;
an optical system including a left-eye optical module and a right-eye optical module, each optical module including an image generator, a partially transmissive curved mirror positioned in front of a viewer eye, and an optical image relay configured to conjugate a two-dimensional (2D) image formed from the image generator to a curved focal surface of the partially transmissive curved mirror and including a prism having a folding surface extending between an input surface and output surface and configured for folding the optical path for light generated by the image generator, and an aperture stop for the optical image relay is formed within the prism;
an inter-pupil distance (IPD) adjustment system including:
a stationary center support mounted to the headset support frame;
a left transport apparatus slideably mounted to the stationary center support and coupled to the left-eye optical module for supporting the left-eye optical module from the stationary center support;
a right transport apparatus slideably mounted to the stationary center support and coupled to the right-eye optical module for supporting the right-eye optical module from the stationary center support;
and
an actuator configured to selectively move the left transport apparatus and the right transport apparatus along a longitudinal axis to adjust an inter-pupil spacing between the left-eye optical module and the right-eye optical module; and
one or more control logic processors programmed to execute an algorithm including the steps of:
receiving the pupil position of the viewer from the eye-tracking system;
operating the actuator to adjust the inter-pupil spacing between the left-eye optical module and the right-eye optical module based on the received pupil position;
receiving image data from the one or more front facing cameras; and
operating each image generator to display the received image data onto each curved mirror.
