In the concrete operation step of embodiment 3, the measuring principle of grating scale are as follows:
In measurement, the long and short two fiber optic ruler face of scale grating 21 and indication grating 224, which is parallel to each other, to overlap, and
0.01 to 0.1 gap is kept, indication grating 224 rotates a small angle, θ relative to scale grating 21 in own layer,
When light ray parallel irradiates grating, due to the transmission and diffraction effect of light, perpendicular with the bisector of two grating strain line angle thetas
Direction on, it may appear that light and shade is alternately spaced equal striped, i.e. Moire fringe, such as Fig. 4；
Due to the interference effect of light, near intersection point a line, the groove of two blocks of gratings is overlapped, and the light transmission on grating is narrow
Seam does not block mutually, and light transmission is most strong, forms bright band；Near b line, one piece of grating lightproof part just covers in another grating
Light transmission slot, light transmission is worst, forms blanking bar；The distance between adjacent two bright bands or blanking bar W are known as the pitch of Moire fringe, figure
5 show the relationship between Moire fringe pitch W and raster pitch ω and inclination angle theta,WhereinThereforeDue to θ very little, when θ unit is rad,Therefore
The moving distance of Moire fringe and the moving distance of grating are proportional, one pitch of grating transverse shifting, More's item
Line moves up and down a pitch ω exactly along groove, in other words a certain position on grating line, as Fig. 4 a line at, More
Striped bright-dark-bright variation a cycle, this provides good condition for the installation of photoelectric cell and signal detection；
Furthermore the moving direction of the moving direction of grating and Moire fringe also has fixed relationship, such as 224 phase of indication grating
One low-angle+θ is counterclockwise turned for scale grating 21, when scale grating 21 right (left side) is moved, then under Moire fringe
(on) move；On the contrary, indication grating 224 turns a low-angle-θ clockwise, when scale grating 21 right (left side) shifting, then More's item
The upper (lower) shifting of line；The moving direction of grating can be distinguished according to the moving direction of Moire fringe.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features,
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
