1. An image display device comprising:

  • a main optical path;

    a housing mountable to a person'"'"'s head;

    an image source associated with the housing and oriented substantially perpendicular to the main optical path, the source adapted to be driven by a remote signal in order to generate an image that is transmitted along the main optical path;

    a beam splitter, positioned in the main optical path and oriented at an angle of approximately 45°

    such that a beam propagating along the main optical path is deviated over a substantially right angle and that the image generated by the image source is focused into the entrance pupil of a human eye of the person;

    at least one lens oriented substantially perpendicularly to the main optical path and placed between the image source and the beam splitter, and configured to amplify, collimate and correct optical aberrations of the said image,wherein the image source and the at least one lens are contained inside the housing,wherein the image source, the beam splitter, and the at least one lens are in an on-axis configuration, andwherein the device further comprises one or two mounting brackets positioned parallel to the main optical path and mechanically connecting the beam splitter to the housing, each of the one or two mounting brackets having a first pivotal mechanism at one end and a second pivotal mechanism at another end, the first pivotal mechanism being attached to the housing and the second pivotal mechanism being attached to the beam splitter.
