## Holographic Display Architectures, Optics, and Systems

Most CGH display frameworks use coherent light source (laser) and a single phase-only SLM. The following works explore alternatives to the current paradigm, such as using partially-coherent light sources, amplitude SLMs, and adding additional optical elements.


<!-- Reducing speckle noise: 1. Superposition 2. Spatial coherence construction 3. Temporal (spectral) coherence destruction -->
Partial coherence (in a general sense) are often deployed to reduce speckle artifacts:
- [Speckle-free holography with partially coherent light sources and camera-in-the-loop calibration](https://www.computationalimaging.org/publications/partiallycoherentholography/) (*Peng et al. 2021 | Science Advaces, Science*) uses partially coherent light sources (i.e. LED) and camera-in-the-loop optimization to reduce speckle artifacts.
