A method for forming large area, uniform efficiency holograms is described which comprises illuminating the hologram area so that the two recording beams are formed, with one recording beam having an odd number of reflections with respect to the other recording beam. The hologram recording can be conveniently accomplished by directing a laser beam 10 to beamsplitter 12 to form recording beams 14 and 16. Recording beam 14 is reflected from mirrors 18 and 20 to direct beam 14 at an angle to recording member 22. Recording beam 16 is reflected from mirror 24 to direct beam 16 at an angle to the recording member 22. As shown in Fig.
