Abstract :

<p>&nbsp;<span style="text-align: justify; font-size: 9pt; font-family: &quot;Times New Roman&quot;, serif;">Cladding of </span><span style="text-align: justify; font-size: 9pt; font-family: &quot;Times New Roman&quot;, serif;">Poly-methyl-methacrylate optical fiber of 1mm diameter is cleaved and optical signal with sine, square and triangular wave is passed through fiber. Cleaved region is immersed in the solution of potassium dichromate, potassium permanganate and copper sulphate solution of different concentration. Peak to peak voltage of the signal at output is found to vary with frequency of the signal. Integrated area of the curves shows variation with the concentration. Concentration of the solution can be calculated directly using the analysis of the signal.</span></p> <p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;text-align:&#10;justify;line-height:normal;mso-layout-grid-align:none;text-autospace:none"><span style="font-size:9.0pt;font-family:&quot;Times New Roman&quot;,serif"><o:p></o:p></span></p>
