Chip-scale atomic clock 芯片級原子鐘
rdfs:comment
芯片級原子鐘（英語：Chip-scale atomic clock，縮寫为CSAC）是使用微机电系统（MEMS）技术制造的紧凑型低功耗原子钟，并结合了低功耗半导体激光器作为光源。基于2001年的一项发明，2003年在國家標準技術研究所上展示了第一个芯片級原子鐘物理软件包。这项工作是由美国国防部国防高级研究计划局（DARPA）资助的，目的是开发一种微芯片大小的原子钟，用于便携式设备。在军事装备中，当全球定位系统不可用时，有望为下岗士兵提供更好的位置和战场态势感知，但也可以设想许多民用应用。这些原子钟的商业生产始于2011年。芯片級原子鐘是世界上最小的原子钟，其尺寸为4 x 3.5 x 1厘米（1.5 x 1.4 x 0.4英寸），重35克，仅消耗115毫瓦的功率，也可以在运行几年后将时间保持在每天100微秒以内。 A chip scale atomic clock (CSAC) is a compact, low-power atomic clock fabricated using techniques of microelectromechanical systems (MEMS) and incorporating a low-power semiconductor laser as the light source.

dbo:abstract
A chip scale atomic clock (CSAC) is a compact, low-power atomic clock fabricated using techniques of microelectromechanical systems (MEMS) and incorporating a low-power semiconductor laser as the light source. The first CSAC physics package was demonstrated at NIST in 2003, based on an invention made in 2001. The work was funded by the US Department of Defense's Defense Advanced Research Projects Agency (DARPA) with the goal of developing a microchip-sized atomic clock for use in portable equipment. In military equipment it is expected to provide improved location and battlespace situational awareness for dismounted soldiers when the global positioning system is not available, but many civilian applications are also envisioned. Commercial manufacturing of these atomic clocks began in 2011. The CSAC, the world's smallest atomic clock, is 4 x 3.5 x 1 cm (1.5 x 1.4 x 0.4 inches) in size, weighs 35 grams, consumes only 115 mW of power, and can keep time to within 100 microseconds per day after several years of operation.A more stable design based on the vibration of rubidium atoms was demonstrated by NIST in 2019. The new design has yet to be commercialized. 芯片級原子鐘（英語：Chip-scale atomic clock，縮寫为CSAC）是使用微机电系统（MEMS）技术制造的紧凑型低功耗原子钟，并结合了低功耗半导体激光器作为光源。基于2001年的一项发明，2003年在國家標準技術研究所上展示了第一个芯片級原子鐘物理软件包。这项工作是由美国国防部国防高级研究计划局（DARPA）资助的，目的是开发一种微芯片大小的原子钟，用于便携式设备。在军事装备中，当全球定位系统不可用时，有望为下岗士兵提供更好的位置和战场态势感知，但也可以设想许多民用应用。这些原子钟的商业生产始于2011年。芯片級原子鐘是世界上最小的原子钟，其尺寸为4 x 3.5 x 1厘米（1.5 x 1.4 x 0.4英寸），重35克，仅消耗115毫瓦的功率，也可以在运行几年后将时间保持在每天100微秒以内。
