The utility model discloses scanning speed is fast, owing to adopted the encoder, the wavelength record is accurate.
Description
Technical field
The utility model relates to a kind of fiber spectrometer optical-mechanical scanning mechanism, belongs to photoelectric mechanical field.
Background technology
The fiber spectrometer mechanicalness of prior art is poor, and sweep velocity is slow, and wavelength accuracy of recording is low, it is dumb to use.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of and records the fiber spectrometer optical-mechanical scanning mechanism accurate, sweep velocity is fast, work efficiency is high.
In order to solve above technical matters, the utility model provides a kind of fiber spectrometer optical-mechanical scanning mechanism, comprises optical fiber, grating, the first slit and the second slit; It is characterized in that: also comprise linkage swing mechanism, described linkage swing mechanism comprises motor, first connecting rod, second connecting rod and scrambler; The rotor of described motor with first connecting rod, first connecting rod and second connecting rod, adopt connection bearing to be connected between second connecting rod and scrambler respectively; Described scrambler is fixedly connected with grating, and described code device signal output terminal is connected with the controller of spectrometer; The mixed light of described optical fiber, by impinging upon on grating after the first slit, is detected device again through the second slit after described grating beam splitting and receives.
The technical scheme that the utility model limits further is:
Further, described scrambler is angular encoder.
Further, described grating is concave grating.
The beneficial effects of the utility model are: the utility model sweep velocity is fast, and owing to have employed scrambler, wavelength record is accurate.Overcome the machine error of existing scanning mechanism, scanning position is controlled by scrambler completely, by connecting rod sweeping, improves sweep velocity, and sweeping angle is determined by link design parameter completely, practical relatively flexibly.
