Abstract

The invention discloses a high-precision pose adjusting device for a spliced grating, and relates to a high-precision pose adjusting device for a grating set. The device solves the problem that the high-precision grating pose adjusting device cannot realize precise grating adjustment of multiple degrees of freedom. A pitch adjusting unit is driven by a pitch adjusting micro driver to drive a pitch adjusting right guide rail sliding block to slide on a corresponding guide rail so as to realize directional independent grating adjustment; a deflection adjusting unit is driven by a deflection adjusting micro driver to drive a deflection adjusting framework and front and rear deflection guide rail sliding blocks to slide on the corresponding guide rails so as to realize directional independentgrating adjustment; an in-plane adjusting unit is driven by an in-plane adjusting micro driver to drive an in-plane adjusting front and rear guide rail sliding blocks to slide on the corresponding guide rails so as to realize independent grating adjustment; and a linear adjusting unit is driven by a linear adjusting micro driver to drive a linear adjusting framework and left and right linear guide rail sliding blocks to slide on the corresponding guide rails so as to realize directional independent grating adjustment. The device is used for high-precision pose adjustment of the spliced grating set.

Description

technical field [0001] The invention relates to a high-precision pose adjustment device for a grating group. Background technique [0002] Large-aperture diffraction gratings play an important role in many technical fields, such as spectroscopic astronomical telescope systems, inertial confinement fusion systems, and synchrotron radiation systems. At present, it is technically and economically impractical to directly manufacture large-aperture high-quality multilayer dielectric film gratings. Therefore, it is important to realize large-aperture high-quality diffraction gratings by splicing several small gratings into a large-aperture grating. means. Generally speaking, a grating compressor needs to be built for the spliced ​​grating group. The grating groups in the compressor need to adjust their relative positions to compress the pulse. The grating position and attitude adjustment device is a key device to realize the precise adjustment of the mutual position relationshi...
