An optical rotation plate has an optical rotation material layer.
Disclosed are an optical rotation measurement apparatus, an optical rotation measurement system, a polarization conversion optical system and an optical rotation measurement method.
Each variable optical rotation member has two deflection-angle prisms formed of an optical material having an optical rotation feature and being capable of moving relatively along a direction crossing the optical axis (AX).
The optical rotation member is formed of an optically rotating optical material, and has its optical-axis-direction thickness changed along a direction perpendicular to the optical axis.
The optical rotation measurement method is performed by using the optical rotation measurement apparatus or system.
An optical rotatory power calculating section (708) calculates the optical rotatory power of the sample (106) from the modulating signal (Vb) and the measured light intensity.
The object is designed as a polarization matrix or as one or several homogeneous, optically rotating substances.
