✦ Synopsis

ⅷ As compared to the Gaussian approach, the point of peak power is higher, and occurs for higher values of h. ⅷ In the ascending flank of the curves, particularly in the range 0.25hrh -0.75 where the sensor sensitivity ref S s Ѩ P rѨ h is higher and linearity errors are smaller, it n is observed that sensitivity values remain practically unaltered irrespective of the approach used.

CONCLUSION

A quasi-Gaussian beam approach has been presented to accurately model the radiation pattern of the light intensity emitted by the transmitting branch of a bifurcated optical fiber bundle displacement sensor. Based on the experimental data of a case study, beam parameters have been evaluated employing a least squares fitting technique. The transfer function characterizing the optical sensor response has been determined using the quasi-Gaussian beam approach, and the results obtained have been compared with those corresponding to a simplistic Gaussian beam modeling.
