Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A holographic lens comprising:
a plurality of positions configured to form an imaging optical system that images lights emitted from a plurality of areas of a light emitting device on a corresponding plurality of virtual image points; and
a phase profile obtained through an optimization process for each position of the plurality of positions,
wherein, according to the phase profile, a phase of each position of the plurality of positions in the holographic lens is formed to have an optimized value satisfying

min∥T·(δ−ρ)−øtarget∥2,

where p is a phase of light emitted from each of the plurality of areas of the light emitting device, Φ is a phase of the holographic lens, δ is a phase of light emitted from a virtual image, T is a projection matrix, and Φtarget is a phase providing an intended virtual image.
