Fiber Optic Gyroscope (FOG): senses changes in orientation. • Laser Radar (LADAR): is employed similarly to millimeter wave radar, but uses laser beams to scans and process the signal echoed from targets. • Light Detection And Ranging (LIDAR): is an optical remote sensing technology that...
17.2.3 Fiber-optic gyros A fiber-optic gyro (FOG) is an RLG with a twist in that the light is directed around many loops of fiber-optic cable (as opposed to a simple enclosed set of mirrors with an RLG). As shown in Figure 17.8, a light source is generated in opposing directions ...

FOG - Fiber-optic Gyroscope Quartz/MEMS Gyroscopes Ring laser gyroscope (RLG) Ring laser gyroscopes operate on the principle of the Sagnac effect. A single laser is split into two beams that move around in the ring in opposite directions. The sensor measures the interference pattern caused by ...
In addition, gyroscopes are important elements in platform stabilization systems (i.e. antenna stabilization) and where accurate pointing and/or targeting is required. Honeywell gyro technologies include: Spinning mass mechanical gyros Fiber-optic gyros (FOGS) ...
Overview of the testing room geometry and cameras’ locations. This figure demonstrates a two-camera setup that could catch any fall in any place inside the room (supported by our test set). (a) Side view. The lower boundary for fall detection was set to be aligned to the lower edge of...

Although the presented analysis was only concerned with orientation error, in addition to bias, it includes an accurate random error model for gyroscopes. However, the gyroscope sensitivity and alignment errors are not considered. A more complex model of the measurement system is presented by [9],...
Fiber Bragg grating (FBG) sensory system; damage detection; structural health monitoring (SHM); deep learning; Convolutional Neural Network (CNN); composite pipelines 1. Introduction In order to meet safety and environmental regulations, it is vital to ensure the reliability of operating gas and ...
A number of recent technologies have brought new forms of gyroscopes, including optical gyroscopes such as laser gyroscopes and fiberoptic gyroscopes as well as mechanical vibratory gyroscopes. Spacecraft generally depend on inertial rate sensing equipment to supplement attitude control. Currently this is...
