It should be noted that the lengths of the arms of the interferometer on ground-based gravity wave detectors are on the order of 1 kilometer.
The downward radiance measured by the infrared interferometer is a combination of thermal emission by atmospheric water vapor and by the cloud ice mass.
The flip causes a tiny shift in the cantilever's vibration frequency, which is recorded by the laser interferometer .
The force is measured with a cantilever spring, and the distance is obtained interferometrically .
Optical interferometers (and other refractive index sensors) have features that make them versatile platforms for biomolecular sensing.
The solution is to use optical interferometry .
Protein concentration was monitored interferometrically at intervals of 10 min.
A separate laser provided interferometric information to measure the field of the signal.
The substrates are moved by a translation stage that is controlled interferometrically .
This technique is closely related to a previous interferometric method for measuring the optical phase-space distribution of a light field.
