  • Measurement of low cell gap and retardation by using a rotating polarizer method was proposed. For more precise calculation and measurement, we applied a retardation film that has large retardation value of $1\;{\mu}m$ to measurement system. From experiments, we proved that cell gap and retardation could be measured even though the values of those are so small.
