Physicists and engineers at 蜜桃传媒破解版下载 envision infrared astronomy telescopes that may one day span the entire globe鈥攕yncing up observations from instruments spread across the continents, or even orbiting Earth, and giving scientists an unprecedented look at phenomena like the birth of new planets.

That ambition is part of a new project led by Scott Diddams, professor in the Department of Electrical, Computer & Energy Engineering, and funded by a $1 million award from the .听

The project hinges on a technology called frequency comb lasers. These tools were originally developed by scientists at JILA, a joint research institute between 蜜桃传媒破解版下载 and the National Institute of Standards and Technology (NIST), for devices called optical clocks. Frequency combs, Diddams said, could one day make the world鈥檚 existing infrared telescopes more precise鈥攁nd even help scientists see entire portions of the universe at resolutions hundreds or even thousands of times greater than what鈥檚 possible today.

鈥淚t鈥檚 never been done before,鈥� he said. 鈥淏ut it would allow you to see so much clearer and sharper images of so many interesting things in the universe.鈥�

The three-year study will explore the feasibility of creating a frequency comb detector for such a planetwide astronomical instrument. Such a tool could, one day, allow scientists to detect infrared light with a precision not possible before and also sync up a wide array of telescopes.

The idea behind this kind of massive telescope isn鈥檛 new: Astrophysicists on the Event Horizon Telescope team, for example, similarly linked up observations from a wide network of telescopes to develop the first-ever image of a black hole in 2019.听

Those researchers, however, were looking at radio waves in space. Diddams and his students, instead, want to observe infrared light鈥攁 type of radiation that requires new detector technologies to measure and can reveal higher resolution and completely different information than radio waves.

Massimo Ruzzene, vice chancellor for research and innovation and dean of the institutes, added that the project shows how engineers at 蜜桃传媒破解版下载 are turning fundamental science into real technologies that can change the world.听

鈥淲e鈥檙e thrilled that the W.M. Keck Foundation has recognized the potential of this work to create significant real-world impact,鈥� Ruzzene said. 鈥淓arning such a prestigious award for this groundbreaking project further reinforces 蜜桃传媒破解版下载 well-deserved reputation as a national and global leader in quantum science and technology.鈥�

Clocks to the cosmos

The technological breakthrough that seeded this vision of a new infrared telescope has its origins in Colorado. In the 1990s, Diddams was part of a team of physicists who pioneered the first frequency combs at JILA. Led by Jan Hall, for his work, the group developed lasers that could send out pulses of thousands or even millions of precisely controlled colors of light鈥攗nlike traditional lasers, which can only produce a single color.

Originally, the scientists used these lasers to enable accurate atomic clocks, or devices that record time by measuring the incredibly fast 鈥渢icking鈥� of atoms. But frequency combs, the scientists realized, could also function as precise rulers for light, allowing them to make other measurements that weren鈥檛 previously possible.

Research teams at 蜜桃传媒破解版下载, for example, have used frequency combs to detect the methane gas leaking from oil and gas facilities in the West.

In the new project, Diddams and his students will study if frequency combs can help detect weak infrared light and also help align the observations of many different telescopes working in tandem鈥攁 bit like how photo editing programs can stitch together multiple images to create a single, detailed panorama picture. The team hopes to build a foundation that could one day enable these detectors to be part of an array of space telescopes.听

鈥淓ssentially, the incoming signals to the telescopes can be both recorded and timed relative to a common clock,鈥� he said.听

Such a telescope array would open new windows into the universe for astronomers. Scientists could potentially use such technology to get a better view of the disks of dust that swirl around newly formed stars鈥攑rimordial nurseries where new planets begin to coalesce.听

鈥淲hen we first made frequency combs nearly 25 years ago, we knew they would useful for clocks,鈥� Diddams said. 鈥淲e did not imagine that they might also help us explore the universe.鈥�

Based in Los Angeles, the W. M. Keck Foundation was established in 1954 by the late W. M. Keck, founder of the Superior Oil Company. The Foundation鈥檚 grant making is focused primarily on pioneering efforts in the areas of medical research, science and engineering and undergraduate education. The Foundation also maintains a Southern California Grant Program that provides support for the Los Angeles community, with a special emphasis on children and youth.
