Abstract

The invention discloses a remote sensing detection translation device, relates to the technical field of remote sensing. According to the invention, a guide correction mechanism is arranged to ensurethe translation precision and prevent the occurrence of angular deflection. Meanwhile, two groups of rolling guide correction mechanisms which are arranged oppositely and two groups of sliding guide correction mechanisms which are arranged oppositely are adopted to prevent the difficult manufacture of sliding blocks and the interference phenomenon of the sliding blocks caused by adopting sliding in all, and avoid the problem of large error caused by adopting rolling. The rolling mechanism can ensure the installation requirement and improve the moving performance, and the sliding coefficient ofthe sliding guide correction mechanism can be adjusted, so that the sliding precision can be ensured according to requirement; and the rolling guide correction mechanism is provided with the staggered rollers, and is matched with the V-shaped grooves, so that the creeping problem in the moving process can be prevented, and the stability of translation is ensured.

Description

technical field [0001] The invention relates to the technical field of remote sensing detection, in particular to a translation device for remote sensing detection. Background technique [0002] For a Fourier spectrometer using a plane mirror as a phase modulation element, it is very important to keep the motion of the plane mirror as a translational motion in order to obtain high spectral resolution. When it works, the moving mirror must move in a straight line with high precision relative to the fixed mirror. The fluctuation of the speed and angle of the moving mirror will reduce the spectral quality. Therefore, the translational motion of the moving mirror is crucial. [0003] The current moving mirror movement is generally driven by a high-precision linear drive. When it is driven, for a large moving mirror, it is difficult to ensure its guiding effect only by using a single guide when it is in motion. When moving, there will be angle deflection, which affects the accu...

Problems solved by technology

[0003] The current moving mirror movement is generally driven by a high-precision linear drive. When it is driven, for a large moving mirror, it is difficult to ensure its guiding effect only by using a single guide when it is in motion. When moving, there will be angle deflection, which affects the accuracy. Although the use of sliders for guidance can ensure accuracy, if four-sided guidance is used, not only is it prone to interference, but also the manufacturing accuracy of the sliders is very high. After installation It is difficult to ensure that the friction force of each slider is uniform, and it is easy to cause deflection. In this way, during movement, the side with small friction force will move faster, causing the angle of the moving mirror to change. If three sides are used for guidance, then Unbalance is easy to appear, and creeping phenomenon is easy to appear during the movement of the moving mirror, which affects the uniform operation of the moving mirror
