The invention relates to a space optical remote sensor
secondary mirror focusing flexible movement mechanism, which belongs to the technical field of space optical
remote sensing. The focusing flexible movement mechanism of the present invention includes: a casing, a top cover covered on the casing, a
secondary mirror flexible support
assembly, a flexible driving mechanism
assembly and a flexible guiding mechanism
assembly arranged inside the casing, and a motor arranged outside the casing— - lead screw assembly. The focusing flexible movement mechanism, on the premise of achieving high rigidity, high strength, high stability, and
high surface precision support for the
secondary mirror of the space optical remote sensor, ensures that it can work in a low temperature environment without backlash and without The
optical focusing of the secondary mirror is realized precisely and accurately, and the position accuracy requirements of the secondary mirror relative to the
primary mirror such as eccentricity and inclination are met by the optical design. The
processing technology and assembly process are simple, the work is reliable, and the maintenance process is exempted.
