  • Publication number: 20190361394
    Abstract: A Volume Bragg grating (VBG) is placed in the back of a collimating lens, the incident angle between exposure light beam and the Volume Bragg grating is equal to the Bragg angle of the Volume Bragg grating. A photodetector is placed in the ?1 grade transmission diffraction light path of the Volume Bragg grating which the exposure light beam is emitted to. The pinhole filter is moved back and forth along an optical axis and the reading of the photodetector is observed in real time. When the reading of the photodetector is maximum, fix the pinhole filter and keep the distance between the first pinhole filter and the first collimating lens a constant. The method for adjusting the self-collimation optical path is provided, using the Volume Bragg grating to detect the parallelism of self-collimation light and substituting for a traditional Moire pattern adjustment method.

  • Publication number: 20110236802
    Abstract: This invention discloses a method for fabricating a holographic grating with low diffractive wave aberrations on a substrate with aberrations. Forming a interference recording field from two coherent beams, where one is a parallel beam and the other is a beam whose wave-front can be controlled, recording the holographic field on the substrate with aberrations, fabricating the holographic grating with low diffractive wave aberrations, setting a deformable minor into one of the coherent recording beams, and controlling the shape of said deformable minor so as to obtain a compensated interference recording field. Expose the recoding plate under the holographic interference recording field which has been adjusted by the deformable minor to record the grating. After developing, the fabrication of holographic grating with low diffractive wave aberration is finished.
