HoloSim is an open-source tool that I helped develop and co-authored an academic paper on under the guidance of Dr. Ali J. Alqaraguhli and Dario Trinagali for the NASA Jet Propulsion Lab. The goal of this tool is to help speed up the process of developing antennas. Holography is a method used to detect deformations in an antenna. It is critical that an antenna remains as smooth as possible, especially for space imagery. Holography is a highly accurate way to identify deformations in an antenna; however, it was previously a slow and unstandardized process. HoloSim addresses this issue by providing users with a way to simulate the holography process accurately, ensuring that adjustments only need to be made once. This will lead to faster development of antennas and more precise space imagery.
