Zusammenfassung:The present invention discloses a light source. The light source has a first wire grid polarizer; a second wire grid polarizer; and a laser configured to emit a linear polarization light beam represented by a transmission direction. A first wire grid polarizing filter is represented by a first linear polarization transmission direction and a first exciter configured to allow the first linear polarization transmission direction to rotate relative to the linear polarization light beam. A second wire grid polarizing filter is represented by a second linear polarization transmission direction anda second exciter configured to allow the second linear polarization transmission direction to rotate relative to the linear polarization light beam. The controller is provided with the first linear polarization transmission direction and the second linear polarization transmission direction to provide linear polarization light with an assigned polarization direction. 公开种光源,其具有:第和第二线栅偏振器;以及激光器,其发射由传输方向表征的线性偏振光束。第线栅偏振滤波器由第线
