title = "High-contrast apodization baffle for instruments onboard solar system exploration missions",
abstract = "Utilized in exploration missions of the solar system. The primary objective of the high-contrast baffle is to reveal atmospheric escape on Mars, while other faint objects around bright sources are potential targets. We diverted heritages studied for exoplanet science and instrumentation to this work. The apodization in this study is realized by an edge with microscopic Gaussian-shaped structures. Simulations confirmed the concept and design of the high-contrast apodization baffle and a lab-scale prototype baffle was manufactured, which comprised a transparent flat substrate and a thin film of aluminum. The experiment was executed using a He-Ne laser with a wavelength of 633 nm. The results obtained show that the apodization by the Gaussian-shaped structure significantly improves the contrast. Achieved contrast is better than 10-6.5and 10-8 at > 0.5° and ? > 1°,respectively, and satisfy the requirement for remote sensing of atmospheric escape on Mars.",
