警惕美帝，（MOIRE）魔眼计划仍在推进（顺便求教太空膜 ...

2010年4月本论坛已经报道了魔眼计划（MOIRE，光学薄膜实时成像的研发计划），该计划过于科幻（自行搜索图片，很牛的），但是该计划似乎并未停止。2011年9月完成第一阶段研发，现正在第二阶段。

魔眼计划是为了适应美国的全球安全需求（fxxk，其他人就危险了），该计划将提供随时随地的大量实时图像——而这种能力美国目前尚不具备。（gzjy掌嘴四十！）目前，美国使用飞机来达到军方的图像信息要求。然而，由于飞机数量以及禁入区域飞行高度的原因，航天器在提供图像信息方面扮演着重要角色，而这些信息是军事计划和军事行动取得成功的关键。

Membrane Optic Imager Real-Time Exploitation (MOIRE)To meet national security requirements around the world, it would be optimal to have real-time images and video of any place on earth at any time—a capability that doesn’t currently exist. Today, aircraft are used to meet much of the military’s imagery requirements. However, because of the quantity of aircraft needed, and because aircraft do not fly high enough to see into denied territories, spacecraft also play a vital role in providing the imagery data needed for successful military planning and operations.

然而，航空器要提供持续覆盖能力还面临艰巨挑战。光学口径的需求，制造的多种极限，以及发射极大精确光学反射镜等诸多困难，意味着在地球同步轨道（GEO，三万六千公里）建立此类系统非常不便，只有那里才能提供持续覆盖能力（看来美帝打算发三四个魔眼上去）。
Spacecraft, however, face different challenges in providing persistent coverage.  The size (aperture) of the optics needed, and the limitations of producing and launching extremely large precision reflective (mirror) optics means it is infeasible to place such a system in geosynchronous earth orbit (GEO), approximately 36,000 kilometers high, where it could provide persistent coverage.
魔眼是同步轨道系统的地面试验计划，使用图案蚀刻的衍射薄膜。该衍射膜能够把光线聚焦到传感器上。魔眼计划开发的较大光学平台技术，将把面密度（与航空器尺寸比较的光学镜片质量）较之目前系统降低四五倍。计划目标将验证大面积薄膜（直径至20米），镜片支撑结构，以及把衍射膜转换为宽带图像的二级光学器件制造技术。
MOIRE is a ground-based experiment of a GEO-based system that uses a lightweight membrane optic etched with a diffractive pattern. The diffractive pattern is used to focus light on a sensor.  The MOIRE program seeks to develop the enabling technologies required for very large optic space platforms that reduce the areal density (the mass of the optics compared to the size of the spacecraft) by 4-5 times of current systems. The program aims to examine technologies for manufacturing large membranes (up to 20 meters), large structures to hold the optics flat, and also demonstrate the secondary optical elements needed to turn a diffraction-based optic into a wide bandwidth imaging device.
魔眼计划始于2010年3月，包括两步。第一步验证项目概念，已于2011年9月完成，第二步进行中。
The MOIRE program began in March 2010 and encompasses two phases. Phase 1 verified the proof of concept for the program design. Phase 2 seeks to reduce many of the risks involved in using diffractive optics for space imaging systems. Phase 2 plans to manufacture a section of a prototype five-meter primary optic, along with the required secondary optics, to demonstrate the optical sub-system in a ground-based experiment. As part of Phase 2 technology risk reduction, MOIRE plans to perform an on-orbit experiment of optical membrane imaging technologies through the United States Air Force Academy’s FalconSAT-7 program. The MOIRE program completed Phase 1 in September 2011 and is currently in Phase 2.

顺便问一个问题，为什么没有膜结构的太空实验室呢？那样就可以用较小的火箭获得大直径的太空舱了。2010年4月本论坛已经报道了魔眼计划（MOIRE，光学薄膜实时成像的研发计划），该计划过于科幻（自行搜索图片，很牛的），但是该计划似乎并未停止。2011年9月完成第一阶段研发，现正在第二阶段。
