ABSTRACT:
A display mechanism is provided particularly for use with a helmet mounted visor upon which an image is to be produced superimposed upon the view being observed through the visor. The area of the visor upon which the image is to be reflected is characterized by being composed of a plurality of partially reflecting surfaces arranged in a serrated manner. The partially reflective surfaces may be either flat so as to reflect radiant energy that is already collimated or may be curved so as to collimate the energy if a non-collimated source is employed. More than one set of serrated reflecting surfaces may be used when more than one superimposed image is desired.
