APLIKASI SENSOR OPTIK INTERFEROMETER MACH-ZEHNDER UNTUK DETEKSI KANDUNGAN GLATIN BABI PADA MAKANAN
Abstract: This paper reported
a design of optical sensor to detect hog’s gelatin by using coupler and
opticalinterferometer. This device have been fabricated by attaching a ring
resonator on one of arm of MachzehnderInterferometer (MZI), therefore other arm
was utilized as the reference waveguide signal. Theexperimental set up was
conducted by launching 1 mW Diode Laser in to input terminal, and the
outputsignals at two terminals was detected by optical power meter. Wave
propagating equations have beendetermined based on coupling mode theory using a
transfer matrix method. These equations were thenused to determine the
fabrication parameter such as coupling coefficient, coupling ratio, and
sensorsensitivity. By applying various sample (hog-oil, ice cream magnum, cadburry
chocolate and a set gravy)on the ring resonator waveguide as sensing area
yielded various optical characteristic for each samples.Experimental results
has shown that there was a similarity between hog-oil and cadburry
chocolateoptical birefringence with the hog’s gelatin characteristic. This
results informed the important informationfor muslim consumer that cadburry
chocolate is categorized as a haram food as explained in quran (QS.Al Maidah:
3)
