REG: Image Enhancing and Processing System for Moire and Holographic Interferometric Studies of Microelectronic Packages

[9318671]这个“自由空间中静止的单个原子粒子（SEPARIS 4）”的提案，是为了继续努力，以接近纯电射频阱中弹性束缚的单个原子离子的光学光谱分辨率和精度的基本极限。目标是精确的；1818年的一部分。过去实现的最佳“精度”和1000天稳定性是1013或小于105。新的“精度”意味着，在同一实验室中，两个不同的小组对同一原子线进行的独立频率测量结果都优于1018，并且长期（108秒或1000天）的稳定性也同样好。这将对基础物理学和宇宙学的测量产生许多影响。由于毫秒脉冲星计时的高度稳定性和太空任务的需要，目前原子钟的精度已经很紧张了。如果没有精确的原子钟，其他脉冲星由于引力辐射造成的质量损失是不可能被观测到的。在离家更近的地方，全球定位系统主要依赖于精确的原子钟。随着越来越多的测量任务被简化为精确的频率测量，计量学的新应用领域似乎是无限的。

9318671 Dehmelt This proposal, "Single Atomic Particle at Rest in Free Space 4 (SEPARIS 4)", is for the continuation of efforts to approach the fundamental limits of resolution and accuracy in optical spectroscopy for an individual atomic ion elastically bound in a purely electric rf trap. The aim is an accuracy of; one part in 1018. The best "accuracy" and 1000-day stability realized in the past is 1013 or 105 less. The new "accuracy" would mean that independent frequency measurements on the same atomic line by two different groups in the same laboratory agree to better than 1018 and long term (108 sec or 1000 days) stability is as good. This would have numerous implications for measurements in fundamental physics and cosmology. The precision of current atomic clocks is already being strained by the extraordinarily high timing stability of the millisecond pulsars and the needs of space missions. The mass loss of other pulsars due to gravitational radiation could not have been observed without precise atomic clocks. Closer to home the Global Positioning System relies crucially on precise atomic clocks. There seems to be an unlimited field of new applications in metrology as more and more measuring tasks are reduced to precise frequency measurement.
