Due to extremely effective advantages of the quantum cascade laser spectroscopy and technology for trace gas detection,this paper presents spectroscopy scanning
Based on the principle of the fiber Bragg grating,a new type of fiber-optic pressure sensor for axial force measurement of transformer winding is designed,which
A time division multiplexing of 106 weak fibers Bragg gratings (FBGs) based on a ring resonant-cavity is demonstrated.A semiconductor optical amplifier is conne
The key technology and main difficulty for optical fiber intrusion pre-waing systems (OFIPS) is the extraction of harmful-intrusion signals.After being processe
A novel distributed weak fiber Bragg gratings (FBGs) vibration sensing system has been designed to overcome the disadvantages of the conventional methods for op
Conventionally,high dynamic-range (HDR) imaging is based on taking two or more pictures of the same scene with different exposure.However,due to a high-speed re
