Patent abstract
Systems and methods of measuring birefringence or retardation are provided. For some embodiments, a system is provided, which comprises a polarizer, an analyzer, a first waveplate, and a second waveplate. The system is configured to obtain light intensity measurements by recursively rotating the second waveplate. The obtained light intensity measurements are retrieved, and a light transmission intensity curve is determined from the light intensity measurements.
