ABSTRACT:
A signal mirror assembly has a laminated sandwich construction and includes a transparent center sighting disk. The disk interconnects a relatively thick plastic front sheet with a thin rear plastic sheet to provide enhanced structural integrity and to eliminate potential interference due to condensation. A retrodirective wire screen provides enhanced viewfinding capabilities and is centered within an opening in the adhesive sheet that bonds the plastic sheets together. Reinforcing rods along the horizontal sides of the mirror are rigidly anchored along a center portion and resiliently connected at opposite ends to limit warping over time while allowing for correction of focus by bending, if necessary. Optionally, the mirror may include foam pads for buoyancy.
