The experiments are a significant step toward next-generation "atomic clocks" based on optical rather than microwave frequencies.

此实验对下一代“原子钟”的产生是重要的一步，下一代“原子钟”将是基于光频而不再是微波频率。

One image of the innermost regions of our universe that is "mapped at microwave frequencies" looks like a badly smudged Polaroid.

WSJ: Book Review: Gravity's Engines

It still bathes the Earth in a near-uniform glow at microwave frequencies, and has a temperature profile that is just 2.7 degrees above absolute zero.

BBC: Planck satellite: Maps detail Universe's ancient light

Add a few circuits with a pinch of software and the sensor-only camera can produce up to ten images per second, but the catch is Duke's only works at microwave frequencies.
