Due to its high resolution and the large measuring range, laser interferometer has been applied widely to the precision industrial measurement and calibration. Fabry-Perot interferometry was often used for the microdisplacement, because of its common optical path structure being insensitive to the environmental disturbances. In the past researches, some kinds of modified Fabry-Perot interferome...

For fiber Fabry-Perot sensor vulnerable to external parameters such as electromagnetic, noise and displacement impact, reducing the problem resilience, research and design new fiber Fabry-Perot sensor with parallel processing capabilities based on the intensity and phase of perception. First, according to various types of external parameters and the degree of interference, established the inten...

Current commercial interferometers reveal excellent measurement performances, because of its major advantage which enables the displacement measurement with the characterization of the high resolution under the large measuring range. FabryPerot interferometer is a compact interferometer with the structure of common optical path. In comparison with the ordinary commercial laser interferometers h...

We report on single-longitudinal-mode and tunable operation of an Er:Y 2 O xmlns:xlink="http://www.w3.org/1999/xlink">3 ceramic laser at ∼2.7 μm using intracavity Fabry-Perot etalons combined with a birefringent filter. The is pumped high brightness, narrow linewidth diode source ∼980 nm g...

Nanostructured photonic materials enable control and manipulation of light at subwavelength scales and exhibit unique optical functionalities. In particular, plasmonic materials and metamaterials have been widely utilized to achieve spectral transmission, reflection, and absorption filters based on localized or delocalized resonances arising from the interaction of photons with nanostructured m...
