NIST has developed a new quantum-based pressure measurement technique using a fixed-length optical cavity (FLOC) that could revolutionize various industries. The FLOC is mercury-free, 20 times smaller than traditional mercury manometers, and can measure pressure changes 36 times smaller. Potential applications include more fuel-efficient commercial flights, higher quality semiconductor chips, and improved defense aircraft performance.
Under a CRADA with MKS Instruments, NIST and industry partners aim to develop portable, cost-effective FLOC prototypes suitable for commercial use. The goal is to reduce the device size to suitcase-portable and cost-competitive with existing technologies within a few years. This collaboration could bring quantum-based pressure measurement technology out of the lab and into real-world applications across multiple industries.
