1. An optical device, comprising:
- a light-transmitting substrate having at least two major surfaces parallel to each other and edges;
a first optical element for coupling light waves located in a field-of-view into said substrate by internal reflection; and
a second optical element for coupling said trapped light waves out of said substrate, characterized in that at least one of said major surfaces is coated with an angular sensitive coating.

Abstract
There is provided an optical device, having a light-transmitting substrate having at least two major surfaces (26) parallel to each other and edges; optical means (16) for coupling light waves located in a field-of-view into the substrate by internal reflection, and at least one partially reflecting surface (22) located in the substrate which is non-parallel to the major surfaces of the substrate, characterized in that at least one of the major surfaces is coated with a dichroic coating.
