Abstract
The paper deals with an optical sensor based on the phenomenon of surface plasmon resonance. It proposes a new geometry of the measurement head, which allows for measurements with both the change in the incident light angle and the change in the wavelength. The proposed sensors can also be used in a parallel and a series configuration, which increases the functionality of the setup, allows for a greater precision of measurements, and eliminates such distracting factors as temperature change. The article presents the results of a computer analysis of the sensor, as well as the analysis of its capabilities.
