Description
Technical Field
The invention belongs to the field of grating copying and splicing and detection thereof, and particularly relates to a position adjusting device.
Background
A diffraction grating is an important light-splitting element. In recent years, large-area gratings are widely used in inertial confinement nuclear fusion reactions and astronomical observations. Due to the limitations of the traditional grating manufacturing method, it is difficult to manufacture a large-area grating in meter scale meeting the use requirements, so a new large grating manufacturing method is developed: and (5) grating copy splicing. In an experiment of grating copying and splicing, an interferometer is required to receive far-field diffraction spots and interference fringes of a spliced grating, the wavefront of the spliced grating is calculated, the splicing posture of the spliced grating is adjusted, finally glue is evenly distributed on the spliced grating, a grating blank is covered, after the glue is solidified at room temperature, the blank is taken down, and copying is completed. In the process, the grating needs to be horizontally placed on a test bed, and the grating cannot move before splicing is completed in order to prevent the change of the splicing posture of the grating.
Existing interferometer placement methods generally include both horizontal placement and vertical placement. When the interferometer is horizontally placed, an optical element to be detected is vertically placed in front of the interferometer, and the surface shape of the element is measured after the posture is adjusted, but the method is not suitable for grating copying and splicing experiments, glue is required to be homogenized for copying after grating splicing is completed, if the grating is vertically placed, liquid glue flows downwards under the action of gravity and cannot be uniformly distributed on the surface of the grating, so that the next grating copying work cannot be realized; when the interferometer is vertically placed, the optical element to be detected is placed under the interferometer for detection, and only one-order diffracted light can be detected according to the placing posture of the grating, but non-coplanarity and coplanarity errors need to be adjusted in an experiment for grating splicing, and zero-order and diffraction-order diffracted lights are detected, and in addition, the position of the grating cannot be changed in order to prevent the change of the splicing posture in the experiment, so that the placing mode of the interferometer is not suitable for the experiment for grating copying and splicing.
