The invention relates to a device for circularly polarized light being synthesized into linearly polarized light to form vector beams. A first polaroid sheet, a quarter wave plate and a first half-mirror are arranged in sequence on the linear light path which is emitted by a laser generator; a first reflecting mirror is arranged on the first transmission light path which is transmitted through the first half-mirror, and a second reflecting mirror is arranged on the first reflection light path which is reflected by the first half-mirror; a 1 / 2 wave plate and a second half-mirror are orderly arranged on the second reflection light path which is reflected by the first reflecting mirror, and the first reflection light path forms a third reflection light path after being reflected by the second reflecting mirror; the second reflection light path is reflected by the second half-mirror after passing through the wave plate, the third reflection light path is transmitted by the second half-mirror, the transmission light path and the reflection light path which pass through the second half-mirror are coincided into a light path, and an extender lens and a second polaroid sheet are arranged on the reformed light path in sequence from left to right. The invention has simple structure and easy manufacture, and linear polarized light can be obtained in an interference field of vision through interfering two beams of elliptically polarized light.
Description
technical field [0001] The present invention relates to a combination of linearly polarized light, in particular to a device for obtaining linearly polarized circularly polarized light and synthesizing linearly polarized light in an interference field of view by interfering two beams of elliptically polarized light to form a vector beam. Background technique [0002] When linearly polarized light passes through an optically active substance, the phenomenon of optical rotation occurs, which makes the vibration plane of the original linearly polarized light rotate. The reason for the phenomenon of optical rotation must be explained from the structure of matter, but according to a principle in vibration, Fresnel believes that any linear simple harmonic vibration can be regarded as a combination of two circular motions of the same frequency rotating in opposite directions. : The linearly polarized light propagating along the optical axis of the crystal can also be regarded as co...
