Abstract

The invention discloses a micro displacement mechanism, a moving mirror interferometer and an infrared spectrometer using the moving mirror interferometer. The micro displacement mechanism comprises a driving mechanism and a driven mechanism; the driving mechanism includes a driving elastic reed group, a driving rotor, an inclined block and a driving stator; the driven mechanism includes a driven elastic reed group, a mirror seat, a driven block, a driven stator and a moving mirror module; the driving rotor and the inclined block are arranged at the movable end of the driving elastic reed group; the fixed end of the driving elastic reed group is fixed through the driving stator; the mirror seat is arranged at the movable end of the driven elastic reed group; the driven block and the moving mirror module are fixed at the mirror seat; the fixed end of the driven elastic reed group is fixed through the driven stator; the driven elastic reed group and the driving elastic reed group are made to be vertical to each other when bearing no external forces; and the driven block movably contacts with the inclined block. The micro displacement mechanism has the advantages of small size, light weight, low cost, stable performance.

Description

technical field [0001] The invention relates to the technical field of infrared spectrum measurement, in particular to a micro-motion mechanism used on an infrared spectrometer, a moving mirror interferometer including the micro-motion mechanism, and an infrared spectrometer including the moving mirror interferometer. Background technique [0002] Infrared spectroscopy is the fingerprint spectral region of a substance, so it is an important means of structural identification of compounds. Through the relationship between the spectrum and the molecular structure and comparison with the standard spectrum, the structure of the compound can be determined, such as speculating whether there are certain functional groups, cis-trans Isomerism, position of substituents, hydrogen bonding and complex formation, etc. The Fourier Transform Infrared Spectrometer is the most important instrument for infrared spectrum detection. The Fourier Transform Infrared Spectrometer can analyze any fo...
