High-contrast apodization baffle for instruments onboard solar system exploration missions

K. Enya A. Yamazaki H. Nakagawa N. Teradab K. Seki N. Fujishiro A. Motoyoshi O. Moriwaki

Proceedings of SPIE - The International Society for Optical Engineering 10706 2018年

©2018 SPIE. 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 heritag...

Laboratory demonstration of a cryogenic deformable mirror for wavefront correction of space-borne infrared telescopes

APPLIED OPTICS 56(23) 6694-6708 2017年

This paper demonstrates a cryogenic deformable mirror (DM) with 1020 actuators based on micro-electrical mechanical systems (MEMS) technology. Cryogenic space-borne infrared telescopes can experience a wavefront error due to a figure error of thei...

Quality evaluation of spaceborne SiC mirrors: The effects on mirror accuracy by variation in the thermal expansion property of the mirror surface

MATERIAL TECHNOLOGIES AND APPLICATIONS TO OPTICS, STRUCTURES, COMPONENTS, AND SUB-SYSTEMS III 10372 2017年

A large-scale lightweight mirror that is made of silicon carbide-based material is required for the coming astronomical and earth observation missions. The influence of the inhomogeneity of the coefficient of thermal expansion (CTE) on specular su...

Cryogenic optical testing of sic mirrors for ASTRO-F and C/SiC composite mirrors for SPICA

Hidehiro Kaneda Takao Nakagawa Keigo Enya Takashi Onaka

Proceedings of SPIE - The International Society for Optical Engineering 10568 2017年

Light-weight mirrors are developed for two Japanese infrared astronomical missions, ASTRO-F and SPICA. ASTRO-F is scheduled for launch in 2005, while the target year for launch of SPICA is 2010. The mirrors of the ASTRO-F telescope are made of a s...
