Abstract
The TOLIMAN space mission confronts the challenge of detecting Earth analogues in the immediate solar neighbourhood by using novel astrometric techniques. This bespoke, low-cost mission will employ a novel optical and signal encoding system, enabling high-precision measurements typically requiring larger instruments. Targeting the Alpha Centauri system, TOLIMAN will utilise an innovative diffractive pupil to mitigate the limitations of a relatively modest satellite and payload infrastructure to make measurements at the extreme precisions required. Here we describe the design and manufacturing of the pupil, which employs liquid-crystal technologies and low CTE substrates, all aiming to render measurements impervious to unavoidable optical distortions and aberrations.

Connor Langford is a Spacecraft Engineer at The University of Sydney. He recently graduated from The University of Sydney with a Bachelor of Engineering Honours (Mechatronic/Space) and a Bachelor of Science (Physics). Throughout his degrees, he worked on research projects in the areas of image segmentation using machine learning, neuromorphic AI as well as all-solid-state batteries. As a part of the Defence Industry Internship Program, he worked for Saber Astronautics to develop capabilities for the National Space Qualification Network. In the latter half of last year, Connor worked for DLR GfR in Germany. DLR GfR are responsible for operating Europe’s Galileo satellite constellation. As a part of his Honours, Connor was responsible for optimising reliability models for the Search and Rescue service. He is currently developing a piezo-driven tip/tilt system and assisting with the development of the front plate optics for the TOLIMAN mission.
