Abstract:
A light source having first and second wire-grid polarizers and a laser that emits a beam of linearly polarized light that is characterized by a propagation direction is disclosed. The first wire-grid polarization filter is characterized by a first linear polarization pass direction and a first actuator for causing the first linear polarization pass direction to rotate relative to the beam of linearly polarized light. The second wire-grid polarization filter is characterized by a second linear polarization pass direction and a second actuator for causing the second linear polarization pass direction to rotate relative to the beam of linearly polarized light. A controller sets the first and second linear polarization pass directions to provide linearly polarized light having a specified polarization direction.
