Symmetrical flexible supporting mechanism

Abstract

In order to overcome the defects that a traditional movable mirror supporting mechanism is short in service life, large in coupling displacement, prone to inclination of a displacement output end face and small in movement stroke, the invention provides a symmetrical flexible supporting mechanism which comprises four movable arms, two fixed bodies and a movable body. The four movable arms are the same in structural size, are connected with the movable body through two connecting bodies in the middle of each movable arm and are connected with the two fixed bodies through compensation bodies at the two ends of each movable arm, the four movable arms are symmetrically arranged in the space relative to the center of the movable body, and every two adjacent movable arms are spaced by 90 degrees; the connecting body and the compensation body on each movable arm are flexible hinges, movement transmission is achieved through the flexible hinges, the advantages of zero-clearance transmission, zero friction and the like are achieved, and the movement precision of the mechanism is effectively guaranteed; and a double-parallelogram nested structure is formed in each movable arm, so that the movement stroke of a movable mirror can be effectively increased, a compensation function is achieved, and the spectral resolution of an imaging spectrometer can be improved. The symmetrical flexible supporting mechanism of the invention has the advantages of simple and compact structure, low cost and long service life.

Description

technical field [0001] The invention relates to the technical field of spectral imaging, in particular to a symmetrical flexible support mechanism. Background technique [0002] Spectral imaging technology is a new type of detection technology integrating optics, precision machinery, electronic technology, computer technology and spectroscopy. It can obtain the spectral information of the target while obtaining the geometric shape information of the target. Interferometric spectral imaging technology is based on the principle of light wave interference. By measuring the interferogram of the target, using the corresponding relationship between the target spectral information and the Fourier transform of the interferogram, the inverse Fourier transform of the interferogram is used to restore the spectral information of the target. Interferometric spectral imaging technology has obvious advantages in the quantitative and qualitative aspects of substances, and is widely used in ...
