Polarimeter for detecting polarization rotation

A polarimeter comprising:

• a light source which outputs light only a measurement object;
• an anisotropic meta surface element, positioned to receive reaction light transmitted through the measurement object, which separates the reaction light into first reaction light having a first polarization and second reaction light having a second polarization, orthogonal to the first polarization;
• a detection unit comprising at least one detector which detects the first reaction light and thereby outputs a first detection signal and which detects the second reaction light and thereby outputs a second detection signal;
• and
• a determination unit comprising a memory and a processor configured to execute software instructions stored in the memory and thereby compare the first detection signal with the second detection signal, and calculate a rotation of polarization caused by transmission through the measurement object.
