High-Precision Measurement

High-Precision measurement serves as the cornerstone of scientific research. It has not only propelled the development of fundamental disciplines such as physics, chemistry, and biology but also plays a vital role in applied fields including engineering, materials science, and nanotechnology. With technological advancements, the requirements for measurement accuracy have expanded from the macroscopic world to the microscopic and even atomic scales, with measurable dimensions ranging from millimeters down to nanometers and beyond.

01 Interferometry

Interferometry is a precision measurement technique based on the interference phenomenon of waves. It utilizes the interference characteristics of waves (such as light, radio, or sound waves) to extract information by measuring the phase differences between waves traveling along different paths. Due to the extremely short wavelength of light, even minute differences in optical path length can be detected and result in significant changes in the interference pattern. Interferometry is widely used in fields such as spectroscopy, astronomy, biomedicine, and materials science.

02 Quantum metrology

Quantum metrology is a precision measurement technique that leverages the principles of quantum mechanics to surpass the limits of traditional measurement methods. It achieves extreme sensitivity in detecting physical quantities by manipulating quantum systems—such as atoms, photons, or solid-state qubits. The applications of quantum metrology are extensive, including but not limited to: precision clocks, quantum navigation, single-quantum-sensitive detection, quantum imaging, and quantum radar systems.
