“…Other applications of the polarization phenomenon are found in food technology, such as the analysis of the effects of impurity in a mixture of olive oil and palm oil characterized by the polarized absorption method. Polarized absorption is based on the absorption of light that vibrates in a certain plane when it passes through the sample [5]. On this basis, it is necessary to develop experimental devices on light polarization for middle school and college students, in order to gain a deep understanding of the theoretical and experimental aspects of the phenomenon of light polarization.…”

This paper describes the development of a light polarization experimental apparatus for a remote laboratory. The apparatus had been developed by controlling the analyzer rotation using a stepper motor controlled via the Arduino. Device control and data acquisition applications were developed with LabVIEW which provides remote control panel facilities and web publishing tools. With the developed apparatus, light polarization experiments about Malus’s law in physics teaching can be carried out remotely via the web. The results of the remote experiment show a good agreement with the theoretical predictions. It is concluded that the apparatus for remote laboratories is suitable for use in online experiment-based physics teaching

Classification of biomaterial using polarization of light at present having difficulty for label-free and direct optical detection. The optical properties of a sample which are profoundly explored through the absorption coefficient, scattering coefficient, anisotropy coefficient and degree of linear polarization (DoLP) are neither simple nor easy to handle. In this study, Angle of polarized light (AOP) is our biggest concern. Neither need labeling procedure nor hardly to measure. Instead of linear polarization, this study determined the angle of polarized light as a potent parameter for polarization measurement at the variation axis of transmitted polarized light. Hence, this work was mainly conducted to identify the angle of polarized light for classification of agarose sample, a three-dimensional crosslinked polymer. In this work, a photodiode acts as a polarized light sensor to read voltage changes due to variable concentrations of agarose samples. At the end of the study, relationships between the Angle of Polarized light (AOP) and concentrations of agarose sample at variation axis of transmitted light were successfully investigated. Our result demonstrated a linear correlation between measured voltage (mV) and the concentration of agarose sample (g/ml) with output polarization behavioral model (AOP, ϴ◦) at variation axis of transmitted light. This outcome concluded that the polarization property of the agarose sample in perspective of angle can be identified at variation axis of transmitted light. Therefore, our polarization measurement-setup with variation axis of light transmission is reliable to determine the polarization property of the unknown three-dimensional structure of tissue-mimicking phantom in the future.
