Compact six-dimensional attitude adjustment platform suitable for optical performance detection of large-aperture optical element

The invention discloses a compact six-dimensional attitude adjustment platform suitable for optical performance detection of a large-aperture optical element, and the platform comprises a pedestal, a lifting adjustment assembly, a Y-axis displacement adjustment assembly, an X-axis displacement adjustment assembly, a deflection adjustment assembly, an inclination adjustment assembly, and a pitching adjustment assembly which are sequentially disposed from bottom to top. The lifting adjusting assembly is used for adjusting the height of an instrument or an element, the Y-axis displacement adjusting assembly and the X-axis displacement adjusting assembly are used for adjusting the transverse position and the longitudinal position of the instrument or the element respectively, the deflection adjusting assembly and the pitching adjusting assembly are used for adjusting the deflection angle and the pitching angle respectively, and the inclination adjusting assembly is used for adjusting the inclination angle.
