Further, the plane of polarization of the incident light is switched by the λ/2 half wavelength plate push-pull mechanism 36.  The mechanism 36 is constituted so that an iron core of a maglatch 29 is assembled with a guide arm integrated with a λ/2 half wavelength plate 35, and an opposite pulse voltage is applied to the maglatch 29, and the plane of polarization is rotated.
