This article demonstrates the use of the Geometric Image Analysis feature to compute multi-mode fiber coupling efficiency. In this review, we critically summarize the multimode interference in TOFs and some of its applications with a focus on our research project undertaken at the Optoelectronics Research Centre of the University of Southampton in the United Kingdom.
