Abstract

A parallel type macro-micro driven raster splicing device with high precision and big caliber relates to a raster splicing device with high precision and big caliber. The invention can solve the problem that China has no raster splicing devices with high precision and big caliber. A two-dimensional moving platform part (7) is fixed on a base (6); the lower end of a movable raster part (1) is hinged with the upper end of the two-dimensional moving platform part (7); a fixed raster part (4) is fixedly arranged on the base (6); a first X-axle linear driver (2), a third X-axle linear driver (9) and a second X-axle linear driver (8) are arranged on the base (6) from top to bottom along the direction of an X-axle in turn; each linear driver is respectively fixedly connected with the base (6) and the raster part (1). The invention has the advantages of compact structure, convenient adjusting, flexible operation and high splicing precision, etc., and can realize the splicing with high precision in five space free directions of the movable raster and a static raster in a large area.

Description

technical field [0001] The invention relates to a high-precision large-diameter grating splicing device, which belongs to the technical field of optical mechanical motion positioning. Background technique [0002] With the rapid development of science and technology, diffraction gratings are gradually being used more and more widely, and the demand for large-area high-precision diffraction gratings is also increasing. At present, my country has successively carried out some large-scale scientific and engineering projects such as synchrotron radiation beamlines, laser nuclear fusion, LAMOST astronomical telescopes, and infrared solar tower spectrometers. In these projects, it is urgent to develop high-quality large-area diffraction gratings. For example, in the "Shenguang" series of laser fusion projects being carried out in my country, the use of chirped pulse amplification technology (CPA) makes it possible to obtain ultrashort pulses with higher energy and higher intensity...
