Abstract: An electro-optical system may include a light source configured to emit a beam of radiation, and a pivotable scanning mirror configured to project the beam of radiation toward a field of view. The electro-optical system may also include a first electrode associated with the scanning mirror, and a plurality of second electrodes spaced apart from the first electrode. The electro-optical system may further include a processor programmed to determine a capacitance value for each of the second electrodes relative to the first electrode. Each of the determined capacitance values may have an accuracy in a range of ± 1/100 to ± 1/1000 of a difference between a highest capacitance value and a lowest capacitance value between the first electrode and a respective one of the second electrodes. The processor may also be programmed to determine an orientation of the scanning mirror based on one or more of the determined capacitance values.
