This paper summarizes the results of an ESA feasibility study of a Wide-Field Optical Infrared Imager (WFI) that would search for Type Ia supernovae at low redshift with the aim to measure the changing rate of expansion of the universe. WFI multi-spectral images of the deep universe could also benefit to many other research area in astrophysics. The WFI payload includes a 2 m class telescope, a 1 square degree field of view imaging camera and a low-resolution integral field spectrometer. A mission concept was identified that consists of

Over the next decade the gravitational physics community will benefit from dramatic improvements in many technologies critical to the tests of gravity and gravitational wave detection. The highly accurate deep space navigation, interplanetary laser ranging and communication, interferometry and metrology, high precision frequency standards, precise pointing and attitude control, together with drag-free satellite attitude control will revolutionize the field of experimental gravitational physics. Deep space laser ranging will be ideal for gravitational wave detection, and testing relativity and measuring solar system parameter to an unprecedentend accuracy. We use ASTROD (Astrondynamical Space Test of Relativity using Optical Devices) with three spacecraft and ASTROD I with a single spacecraft as examples for application those technologies. In this paper, we will present the scientific goals and optical requirements of the different mission scenarios, and will summarize the progress of ASTROD / ASTROD I mission studies with emphasis on optical interferometry, the acceleration noises, drag-free attitude control and low-frequency gravitational wave sensitivity.
在接下来的十年里，引力物理界将受益于许多对重力和引力波探测测试至关重要的技术的巨大进步。高精度的深空导航、行星际激光测距与通信、干涉测量与计量、高精度频率标准、精确指向与姿态控制以及无拖曳卫星姿态控制将给实验重力物理领域带来革命性的变化。深空激光测距将是理想的引力波探测，测试相对论和测量太阳系参数，以前所未有的精度。以ASTROD (astrodynamic Space Test of Relativity with Optical Devices)和ASTROD I (ASTROD I with single spacecraft)为例，对这些技术进行了应用。本文介绍了不同任务场景下的科学目标和光学要求，总结了ASTROD / ASTROD I任务的研究进展，重点介绍了光学干涉测量、加速度噪声、无拖曳姿态控制和低频引力波灵敏度。
