A fiber-optic sensor of curvature is made with the sensitivity sufficient to make it ideal for measurement of deflection of structures under mechanical loading. Typically, deflection-curvatures are extremely small, with the curvature-radii in the kilometre range. Although this sensor is intensity modulated,
This thesis concerns the fabrication, characterization, and application of fibre Bragg gratings (FBGs). Being in-fibre wavelength-selective reflectors, FBGs have wide applications in optical communication and sensing systems. Compared with conventional bulk-optic gratings, FBGs offer the advantages of low loss, polarisation independence, compatibility
A problem in modern command and control situations is that much data is available from different sensors. Several sensor data sources also require that the user has knowledge about the specific sensor types to be able to interpret the data.To alleviate the
This master’s thesis presents the development of a collision handling function for Motoman industrial robots and investigates further use of the developed software. When a collision occurs the arm is to be retracted to a safe home location and the job is
