A four-dimensional adjustment device for large space optical remote sensor

Abstract

The invention provides a large space optical remote sensor four-dimensional regulating device, and belongs to the field of pose regulating devices used for ground installation and calibration of large precise optical equipment. The device comprises a bearing frame, a sliding block rocker type turning mechanism, two multi-foot type air floation supporting mechanisms, a spherical secondary supporting mechanism, a torsional pendulum regulating mechanism, a torsional pendulum keeping mechanism and a heavy load transitional motion assembly. When the device is used, the operation risk of an optical remote sensor in an installation process is low, and a pitching motion range is large when the pose is regulated; the multiple air feet are connected in parallel for use, the creeping phenomenon is effectively eliminated, and torsional pendulum regulating accuracy is improved. A fixed transitional motion supporting point is used in cooperation with an air floatation supporting point to constitute a four-dimensional small-route driving system having the high-resolution fine-tuning function, the device can meet the high-resolution pose regulation requirement for the optical remote sensor of optical detection, the shafting structure is greatly simplified, and installing and regulating difficulty is lowered. The device is small in appearance size, low in rotating center of gravity, short in production phase, capable of being used for the fields of installing, fixing, position pose regulating and the like of large space optical remote sensors.

Description

technical field [0001] The invention belongs to the field of position and posture adjustment devices for ground installation and calibration of large-scale precision optical equipment, and in particular relates to a four-dimensional adjustment device for large-scale space optical remote sensors. Background technique [0002] Space optical remote sensors are large-scale precision optical devices, which need to be installed, adjusted, tested and calibrated on the ground before being sent into space. The existing methods usually use a large-scale precision two-dimensional turntable with a linear or arc guideway as the main guiding mechanism to fix the space optical remote sensor, so that the pitch and yaw of the space optical remote sensor on the fixed reference plane can be realized through the large-scale precision two-dimensional turntable operate. [0003] However, with the increasing demand for ground reconnaissance and mapping, the volume and weight of space optical remo...
