Since the basic optical rotation spectrum measurement method need to measure the optical rotation for each wavelength, it takes a long time to measure the spectrum, and it is difficult to acquire the spectrum following the temporal change of the object.
In this study, we verified optical rotation measurement that does not require any mechanical operation by using a kind of ring-type diffractive gratings that utilizes the periodic modulation of the refractive index anisotropy based on the molecular arrangement. It allows to simultaneously measure the angle of optical rotation and the optical rotation spectrum of multiple wavelengths from the intensity distribution of the diffracted light.
