Abstract Scope |
Spatial Light Modulators (SLMs) are devices that manipulate light via phase/intensity-altering pixels. A recent alternative design involves creating a phase mask by directing a thin film of fluid with thermocapillary
forces generated by a controlled temperature map. However, determining the required input temperature for a specific height profile proves challenging due to the intricate thin film equation governing temperature-height relations. To solve this, we employ deep neural networks, crafting equivariant models with scale and rotation symmetry. These models outperform non-equivariant counterparts in accuracy and computational efficiency, addressing the numerical challenges associated with the thin film equation. Beyond offering insights into the temperature-height relationship, this research holds implications for numerous applications, particularly in high-power laser systems. Its success demonstrates more efficient and effective ways to deploy the process of modulation of light in SLMs in a variety of applications. |
