  3. Abstract:
  4. In this study simulation results for three double-fiber optical designs for the reflection measurements are reported. Modeling is perused for three cases namely Equal Fibers (EF), transmitter fiber shorter (TS) and receiver fiber shorter (RS) designs. By proper modeling and written programs the operations of such symmetric double-fiber probes are simulated and the role of different crucial parameters such as fiber-to-fiber distance (t), fiber core radius (r) and fiber Numerical Aperture (NA) are investigated. In the second study simulation results for the transmitter fiber shorter and receiver fiber shorter designs are investigated for different fiber length differences (w). Finally simulation results for the three different designs of equal fibers, transmitter shorter and receiver fiber shorter probes are compared and optimum conditions are described. All three arrangements simulated here offer valuable results for sensing operations such as reflection or displacement measurements. However, the RS probe geometry offers a better design with the less dead region in comparison with the EF and TS designs
