NIST unveils chip-based light 'tape measure' for portable atomic clocks

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new chip-based device that functions as a miniature tape measure for light, enabling high-quality optical measurements without bulky lab equipment. This innovation, created by scientists at NIST and the Joint Quantum Institute, utilizes microchip frequency combs to generate precise, evenly spaced colors. These combs are crucial for optical atomic clocks, and this portable version could significantly advance mobile timekeeping for applications ranging from drone navigation to resource exploration, especially in GPS-denied environments. AI

IMPACT This technology could enable more precise navigation for AI-powered autonomous systems in GPS-denied environments.
