Birefringence measurement optical system and high spatial resolution polarimetric apparatus

摘要: The object of the present invention is to measure amount birefringence a target while enhancing spatial resolution. A measurement optical system comprised Stabilized Transverse Zeeman Laser emitting laser beam in predetermined polarization state toward target, halfwave plate (polarized light emission system), linear polarizer detection system) detecting information on retardation, main axial direction and rotation angle as signal which can be polarimetrically analyzed through photo detector converting from into an electric signal. An fiber (light transmission path) taking out part fluxes optically transmitting detector, arranged between target.
