Projection assembly

A projection assembly comprising:

• a first holographic projection channel configured to form a first holographic light field from a first hologram of a first image;
• a second holographic projection channel configured to form a second holographic light field from a second hologram of a second image;
• and
• a beam combiner configured to receive the first holographic light field on a first side thereof and the second holographic light field on a second side thereof, wherein each hologram is configured to form a holographic light field in which content of a corresponding image in a first dimension is encoded by angle such that angular channels of holographic light each correspond to a respective slice of the corresponding image in the first dimension, and wherein the projection assembly is arranged to use the beam combiner to combine a first plurality of angular channels of the first holographic projection channel and a second plurality of angular channels of the second holographic projection channel in the first dimension in order that the first holographic light field and second holographic light field are co-receivable and transformable into an extended image comprising the first image adjoined to the second image, wherein the beam combiner comprises a beam splitter arranged to receive the first holographic light field on a first side thereof and the second holographic light field on a second side thereof, and wherein the beam splitter is configured to:
• split the first holographic light field into a first transmitted light field and a first reflected light field;
• split the second holographic light field into a second transmitted light field and a second reflected light field;
• merge the first transmitted light field with the second reflected light field thereby forming a first multiplexed channel of two multiplexed channels;
• and
• merge the first reflected light field with the second transmitted light field thereby forming a second multiplexed channel of the two multiplexed channels, wherein the first and second multiplexed channels are identical to each other.
