Abstract
An apparatus, system, and method for a hologram recording system include a recording medium, a light source, and optical elements. The recording medium is configured to record a hologram. At least one light source is configured to provide a writing beam. The optical elements are positioned in a light path of the writing beam and are configured to condition the writing beam to record the hologram at least partially in the volume. The optical elements may include at least one toric optical element and a mirror. The toric optical element may be configured to subtract a quadratic phase from a wavefront of the writing beam, and the mirror may be configured to subtract a linear phase from the wavefront of the writing beam.
