It is featured as setting magnetooptical glass body in magnetic field generated by uniform magnetic field generator, making end surface of said glass body to be planar form and sticking lens on end surface of it.
Description
One, technical field
The present invention relates to a kind of magnetic cycloning device of spherical wave.
Two, background technology
In optical field, utilizing the optically-active characteristic of magnetic rotation material to be used for the principle of polarization direction of quantitative change polarized lightwave has been applied in the important optical element such as optoisolator, because Faraday effect is relevant with the light wave transmissions direction with magnetic direction, therefore practical similar device mostly is applied in the isolation and polarization optically-active of plane light wave, and does not appear in the newspapers yet at present at the rotatory device of spherical wave isolation and polarization optically-active.
Three, summary of the invention
The invention solves in the background technology not at spherical wave and isolate technical matters with the rotatory device of polarization optically-active.
Technical solution of the present invention is: the present invention is a kind of magnetic cycloning device of spherical wave, its special character is: this magnetic cycloning device of spherical wave comprises that magnetic rotation glass body, lens and the uniform magnetic field made by the magnetic rotation material produce body, the magnetic rotation glass body places uniform magnetic field to produce the magnetic field that body produces, magnetic rotation glass body end face is the plane, and lens are affixed on the magnetic rotation glass body end face.
Said lens is two, makes the sphere of two lens be affixed on magnetic rotation glass body both ends of the surface with one heart.
Said lens is one, and lens are affixed on the magnetic rotation glass body end face, and its spheric curvature center overlaps with the non-lensed endface that mounts of magnetic rotation glass body.
The direction of the uniform magnetic field that above-mentioned magnetic field generating body produces is vertical with magnetic rotation glass body end face, and the light wave direction is identical with magnetic direction when making the magnetic rotation glass body place magnetic field.
Above-mentioned magnetic rotation glass body is a cylindricality.
Above-mentioned magnetic rotation glass body is cylindrical.
Said lens by the magnetic rotation coefficient little and refractive index under provision wavelengths, make with the optical material that the magnetic rotation material of magnetic rotation glass body is complementary.
Be provided with polaroid before the above-mentioned magnetic rotation glass body.
It is electromagnet or permanent magnet that above-mentioned uniform magnetic field produces body.
The present invention has utilized the Faraday effect characteristic relevant with the light wave transmissions direction with magnetic direction, the one magnetic rotation glass body of being made by the magnetic rotation material is placed magnetic field, make magnetic direction identical, get the concentric lens that the magnetic rotation coefficient is very little and refractive index is made with the optical material of above-mentioned magnetic rotation match materials simultaneously under provision wavelengths with the light wave direction.Two case of lenses: two mirrors are affixed on the cylinder two ends, and make the sphere of two lens concentric, single case of lenses: make the spheric curvature center of single lens overlap with the non-lens surface that mounts of magnetic rotation material, accomplish that the incident spherical wave comes in and goes out with one heart, its direction of propagation does not change.And the polarization direction anglec of rotation on whole corrugated keeps identical, does not introduce any optical aberration simultaneously.When placing polaroid more in the present invention, the thickness and the uniform magnetic field of design magnetic rotation glass body produce the magnetic field intensity that body produces, and make spherical wave produce 90 degree polarization direction rotations by this device with one heart two times, can realize that then the light of spherical light wave is isolated.Therefore the present invention makes spherical light wave rotatory polarization direction accurately, solved the accurate optically-active problem that before can not handle spherical wave, reduced the design limit of laser instrument manufacturing and optical fiber communication equipment, might for its improve the quality and performance technical support is provided.The present invention can be applicable to the movable phase interfere technology, be used to measure the detection of spherical optics part and optical system, the light polarization modulator of alternative Feisuo type dynamic laser wavefront interferometer, become the dynamic interferometer of light path fully altogether, solve the dynamic interferometer of Feisuo type and can't be designed to the shortcoming of light path form fully altogether, eliminated it because of the non-intrinsic systematic error of light path altogether, range of application with the dynamic interferometer of Feisuo type sphere enlarges greatly thus, can avoid using in the dynamic interferometer of Feisuo type the dual-polarization sheet, improve the orthogonality of the polarization direction of two-way interference light, improved the precision of its polarization interference phase shift.The present invention has simultaneously reduced the part number of instrument, and improved the stability of instrument, and because its interferometer part is changed very little to Feisuo type form, therefore the focus planardetector that can simply change standard lens and carrying space polarization phase shift function according to this principle can be transformed into original interferometer to shaking insensitive dynamic interferometer, has saved expense thus greatly.
