The objective of the research presented in the paper is the selection of suitable probe radius correction method in the case of coordinate measurements of a turbine blade. The investigations are based on theoretical analysis of geometric data and on further computer simulation of measurements and data processing. In the paper two methods for computing coordinates of corrected measured points ar...

The fundamental mechanism by which speckle noise is generated in laser vibrometry before describing a new numerical simulation for prediction of speckle noise level in a real measurement is considered. Factors within the simulation include rate of change of phase within individual speckle transitions, low-pass filtering to match the frequency range of experimental data with which comparison is ...

Capacitive tactile sensors are constructed and installed to the ngers of the HKUST hands for measurement of position, force and direction of principle curvature of contact point. The hardware and software for signal processing are designed such that the contact information is sent to the motion control computer in real time. Experiments in rolling and sliding contact motions are then performed ...

Three different types of strain and temperature sensors based on negative curvature hollow core fiber (NCHCF) are proposed. Each sensor is produced by splicing a small section the NCHCF between two sections single mode fiber. Different interferometers obtained simply changing conditions. The first consists Fabry-Perot interferometer (FPI). remaining configurations attained with same sensing str...
