Methods, apparatus, devices, subsystems, and systems for holographically displaying three-dimensional objects are provided. In one aspect, a device includes: an optical guiding device configured to guide light to propagate along a first direction within the optical guiding device, an in-coupling diffractive structure configured to diffract the light to propagate in the optical guiding device, and one or more out-coupling diffractive structures arranged downstream the in-coupling diffractive structure along the first direction and configured to diffract at least part of the light out of the optical guiding device along a second, different direction. The in-coupling diffractive structure is configured to cause a first optical dispersion for the light, and at least one out-coupling diffractive structure is configured to cause a second optical dispersion for the light. The first and second optical dispersions are compensated, such that light diffracted out of the optical guiding device has no or little optical dispersion.
