Guide Method for simultaneous measurement of velocity and direction of fluid
Fiber-optic method for measuring the velocity of a liquid flow was presented. An array of three FBGs was used as a sensitive element, which made it possible to study the flow direction.
Guide In-line laser Doppler velocimeter using fibre-optic Bragg grating
An optical fibre-linked probe head is used to couple the laser beam at 514.5 nm to and from the measurement volume. The velocimeter is characterized by measuring the velocity of a
Guide Detonation Velocity Measurement with Chirped Fiber Bragg Grating
In this paper, a detonation velocity method using CFBGs was described. We set up a dual-channel CFBG velocimetry and measured the detonation velocity inside a certain explosive cylinder and
Guide Step by step using Fiber Bragg Grating (FBG) sensors
Connect the sensors to the interrogator using optical fibers. The interrogator sends light through the fiber and analyzes the reflected wavelengths from the FBG sensors.
Guide The Liquid Velocimeter Based on Fiber Bragg Gratings
The novel fiber velocimeter is proposed by using a special packaged-structure combined with two fiber Bragg gratings for sensing a differential pressure which is resulted from a fluid flowing.
Guide Embedded fiber-optic Bragg grating (FBG) detonation velocity
Figure 5 A tungsten probe, heated to 70°C is used to non-destructively measure the location and physical length of a fiber-optic Bragg grating. A high resolution translation stage was used to
