Research of Fiber Bragg Grating Sensor Demodulating

Combining the virtual instrument technology with the fiber Bragg grating sensing technology, a new fiber Bragg grating sensing demodulation system based on Lab VIEW has been designed. The unbalanced Mach-Zehnder interferometer demodulation technology has been used in this system to translate the fiber Bragg grating wavelength signals in which the strain information is contained into the phase

When Sand-Slithering Snakes Behave Like Light Waves

When Sand-Slithering Snakes Behave Like Light Waves

Desert snakes slithering across the sand at night can encounter obstacles such as plants or twigs that alter the direction of their travel. While studying that motion to learn how limbless animals control their bodies in such environments, researchers discovered that snakes colliding with these obstacles mimic aspects of light or subatomic particles when they encounter a diffraction grating.

Fiber Bragg Grating Sensor for the Research of Water Level

Fiber Bragg Grating Sensor for the Research of Water Level

In hydraulic engineering, hydrology and water conservancy departments focus on the water level measurements of reservoir. Water level sensor is very important to water level measurements of reservoir. This paper designs a water level sensor which is combined with elastomeric membrane and fiber grating, to eliminate the impact of temperature on the sensor through the use of self-compensating

When Sand-Slithering Snakes Behave Like Light Waves

Snakes slithering across the desert sand at night can encounter obstacles such as plants or twigs that alter the direction of their travel. While studying that motion to learn how limbless animals control their bodies in such environments, Georgia Tech researchers discovered that snakes colliding with an obstacle behave much like light waves encountering an optical diffraction grating.
