The Korea Research Institute of Standards and Science (KRISS) has developed a revolutionary optical frequency comb system that measures distances with 0.34 nanometer precision—close to the fundamental quantum limit—at speeds of 25 microseconds. This could redefine global standards for ultra-precise metrology in semiconductors, quantum tech, and beyond. Here’s why it’s groundbreaking:

⚡ Key Innovations:
✔️ Combines lab-grade precision with field-ready speed (25 µs/measurement)
✔️ Optical frequency comb (OFC) interferometry – like a "quantum ruler" with thousands of laser "keys"
✔️ Solves single-wavelength limits: Measures long distances without stitching data
✔️ 10,000x more precise than industrial ToF lasers (micrometer → nanometer!)

🌐 Why This Matters for Tech:

AI chips & quantum devices demand atomic-scale accuracy

Could become next-gen "meter" standard for nations

Compact & robust – works outside labs (unlike current standards)

🔧 How It Works:
1️⃣ OFC laser fires thousands of precise frequencies
2️⃣ Spectral interferometry analyzes reflections
3️⃣ Quantum-level math extracts 0.34nm resolution

🇰🇷 KRISS’s Vision:
"Future industries depend on nanometer control," says lead researcher Dr. Jang Yoon-Soo. This tech could cement Korea’s leadership in quantum-era metrology.
