“…The value  vs. V is polynomial in 2 nd order as has been obtained also in our previous study [18][19][20][21][22] as nonlinear optics characteristics. The value /V, which is supposedly proportional to the potential energy of Lenard-Jones, is very surprising.…”

“…Through the electrooptic effect, it has been known that nonlinear optics in cooking oils can also be observed by measuring the change of light polarization, and this opens up new horizons and potential possibilities in the development of cooking oil quality evaluation along with the study of the interaction of light with matter [15][16][17][18][19][20][21][22]. Since the oil quality parameters accompanied by their methods or instruments are usually too many and complex, then there needs to be such a new idea that it is possible to obtain a single quality parameter [16,17].…”

The interaction between triglyceride molecules in cooking oil can be described by Van der Waals interaction which the potential energy between molecules is fulfilled by the potential energy of Lenard-Jones. This study aims to obtain relative dissociation energy in palm oil and animal oil using electro-optics polarization. In the experiment, we measured the change of light polarization as the sample was induced by potential difference or so-called electro-optics. The relative potential of Lenard-Jones as a function of the relative molecular distance was assumed proportional to the average change of electro-optics polarization as a function of potential difference. The results show that in this experimental condition, palm oil has relative dissociation energy greater by a factor of 100 than animal oils, and it decreases after the sample is heated. The observation of Van der Waals interaction through the electrooptic polarization is a new perception and it relatively can be achieved by using a simpler polarization experiment.

“…Starting from it, polarization learn a lot and has many usages in experiments until now. In several previous studies [2][3][4][5][6][7][8], by adding electrooptical polarization (non-linear optics), light polarization can also be applied to characterize the optical properties of several other materials, such as cooking oil, whose active optical properties are relatively very small. By setting the observation direction to fluorescent polarization [9][10][11], light polarization can also be used to identify various cooking oil types and evaluate pork oil contamination.…”

This paper has carried out active and non-linear optical characterizations of motor vehicle lubricants. The samples used were three two-wheeled vehicle oil with SAE labels: 10W-40, 20W-50, and 10W-30 without pre-treatment. The active optical property (natural polarization) was measured as a function of the polarizer angle without external field interference. Meanwhile, non-linear optical properties (electro-optical polarization) used changes in the polarization of light as a function of the potential difference imposed on the sample. The light sources used were a green pointer laser (532 nm) and a red pointer laser (632 nm). The results showed that the oil has active and non-linear optical properties. The natural polarization characteristic produces two polarization peaks at 30° and 60° on both wavelengths and holds to all samples. It indicates that the dimensions and shape of the molecules in all samples are identical. It is also shown by electro-optical polarization, where the change in polarization acts as a quadratic function of the potential difference with the concentric curves of the three samples, indicating identical molecules. With electro-optical polarization, the total polarization is enhanced without changing the active optical properties in the sample. It gives an advantage for developing this method as a tracer and evaluator of the molecules of other relevant materials.
