Abstract

The invention discloses a polarization-maintaining reflection angle adjustable device. The device comprises a base, wherein a first 1 / 4 wave plate is arranged on the base, a rotating device is arranged above the first 1 / 4 wave plate, a reflection device is arranged above the rotating device and fixed with the rotating device oppositely, and a second 1 / 4 wave plate is arranged at the top of the rotating device, opposite to the first 1 / 4 wave plate and located right above the first 1 / 4 wave plate. The invention further discloses an adjusting method of the polarization-maintaining reflection angle adjustable device. The device can perform polarization-maintaining reflection on incident light and the polarization state of reflected light can deflect at any angle.

Description

technical field [0001] The invention belongs to the field of optics, and in particular relates to a device with adjustable polarization maintaining reflection angle and an adjustment method thereof. Background technique [0002] In some optical systems, the optical path is often deflected, and in some systems with polarization requirements, a phase delay is often generated when the optical path is deflected, resulting in a change in the polarization state after the optical path is deflected. If it is necessary to ensure that the polarization state remains unchanged, it is often necessary to form a specific angle between the polarization state of the incident light and the mirror to achieve polarization maintenance, which makes there are many limitations when building the system, and in many cases the free deflection of the optical path cannot be achieved . [0003] The polarization state of the incident light can be changed by using a 1 / 4 wave plate, such as the Chinese pat...
