Sensing biodiesel and biodiesel-petrodiesel blends

This work describes two approaches for refractometric sensors based on cascaded long period gratings for evaluating substances with refractive indices equal to or higher than the fiber cladding at room temperature. The devices are experimented on the assessment of fuel quality regarding the presence of remaining vegetable oil in biodiesel, as well as to determine the concentration of biodiesel in the biodiesel-petrodiesel blends.
