  4. Abstract:
  5. Design and operation of an opto-mechanical system employing a double-cell is reported here for the color liquid reflection studies. The reported system consists of a double-fiber optical design and an electro-mechanical scanning system. In this arrangement one fiber transmits the source light to the object surface and the second one transmits the light reflected from the sample to a photodetector. By scanning the double-fiber assembly in one-direction reflection properties of different color liquids are investigated. Reflection signals depend on the cell surface structure and the cell filled material. Two sets of flat/cylindrical cells made of almost similar glass materials are used for this experiment and reflection signals are compared for different filled color liquids. Our results show that the reported system can be used effectively to recognize the liquid color in both types of cells. Comparing the scan results a correlation between the cell width and the reflection curve bandwidth is obtained. In another study the precision, sensitivity, and the reproducibility of the reported system for the cylindrical and flat surface cells are investigated. A reproducibility error of 1.02% is obtained in the reflection measurement results for the reported optical system
