| The present invention relates to an apparatus for providing orthogonally polarized light beams for use in precision metrology applications such as in the measurement of length or length changes using interferometric techniques. An input beam (18) is introduced to a multifaceted anisotropic optically active acousto-optical crystal (47) for travel through an interactive region, it experiences two acoustic beams that diffract it via small angle Bragg diffraction to form two orthogonally polarized internal beam components that are separated by a small angle of divergence and subsequently become external beam components (30, 31) available outside of the acousto-optic crystal (47) for use in anticipated downstream applications. The acousto-optic crystal (47) preferably is a uniaxial crystal comprising TeO2. The degree of overlap or spatial separation between the energy flux profile of the orthogonally polarized, external beam components may be controlled by refracting properties of the acousto-optic crystal (47), its birefringence, the acoustical and optical properties of the acousto-optical crystal (47), the length of the physical path of travel experienced by the emergent beam through the acousto-optical crystal (47) and external birefringent elements. Thermal compensation may be provided via the control of the frequency of the first and second oscillators and/or the properties of the external birefringent elements. | ||||||
