Embodiment Construction
[0026] Embodiments of the present invention propose an optical rotator and a device and method for suppressing laser speckle based on the optical rotator. The technical solution utilizes the diversity of polarized light to suppress speckle. Specifically, this technical solution uses an optical rotator to rotate the polarization direction of the linearly polarized light, so that the rotated linearly polarized light is orthogonal to the linearly polarized light before rotation; the speckle pattern generated by the linearly polarized light before rotation and The speckle pattern generated by the rotated linearly polarized light is superimposed within the integration time of the human eye, so that the speckle is effectively suppressed.
[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conju...
