OSI-S is an ultra-high distributed optical fiber sensing instrument. The principle is optical frequency domain reflection (OFDR). It has the characters of high spatial resolution and high accuracy. The measuring accuracy of OSI-S is ±0.1℃ or ±1.0 micro...
In machinery, aerospace, electric power and other industries, the need of metal surface temperature monitoring is very common, such as power cable lines, high temperature steam pipes and so on. Through temperature monitoring, other physical quantities marked by...
As a truss with high strength, uniform material and easy installation, steel girder truss is often used as the main load-bearing structure for industrial engineering and civil buildings, such as roofs, bridges and pylons. Due to the long-term...
In the pipe clay soil deformation monitoring test, cohesive soil was added to the test box, four sensing fibers were buried and finally the box was left for three months to form a test model. Figure 1 Formed...
During the use of the bridge, due to adverse effects such as environmental load, fatigue effect, material aging and corrosion, etc., its structure will inevitably cause damage and cracks, resulting in a series of safety hazards. Figure 1...
The OCI1500 can be used to measure length, loss and other applications of a silicon optical waveguide. There are many waveguides on the 1.5*1.5cm silicon wafer which is shown in Figure 1. The light goes through waveguide via...
Whispering gallery mode resonator has the characteristics of frequency selection, optical modulation and can greatly enhance the transmission density of the light in materials. It is widely used for wavelength selective absorption and optical interconnection modulator. Figure 1....
OCI1500 can be used to measure grating microstructure and spectrum, and evaluate the quality of gratings. The following figures show the measurement results of four gratings. Each fiber has three complete gratings. The length of gratings shown by...
Planar waveguide optical delay line has the advantage of small size and easy integration. Not only the length of the waveguide can be precisely designed to control the delay time, but also super long waveguide line is able...
OCI1500 is based on OFDR technology and is suitable in short distance, high resolution and high precision measurement areas. When analysis of internal structure of an optical module, OCI1500 can accurately identify the return loss value of all...
