Abstract
The invention belongs to the field of holography and specifically relates to an idle stroke error elimination method for holographic unit printing. According to the method, two realization modes are employed. A former mode is a non-S shape walking mode of a displacement platform, and when line exposure of holographic units is carried out, the displacement platform needs to return to a zero position of a photoelectric switch in the horizontal direction. A latter mode is an S shape walking mode of the displacement platform, and when the line exposure of holographic units is carried out, the displacement platform needs to carry out idle stroke error compensation in the horizontal direction. The idle stroke error elimination method for holographic unit printing provided by the invention is simple and efficient, splicing errors among the holographic units can be reduced, and the reproduction quality of a hologram is improved.
Description
Technical field
The invention belongs to holography field, and in particular to the idle running error removing method that holographic cell is printed.
Background technology
At present existing hologram type method mainly includes that write-through laser printing and synthetic hologram are printed, and the former is first
Using computer simulation object light and the interventional procedures of reference light, obtain calculating after hologram fringe, hologram fringe is divided into some
Holographic cell, by after spatial light modulator loading, directly exposure recorded on holographic dry plate holographic cell；The latter is regarded some
Difference image is loaded onto successively spatial light modulator, and with another road reference light physical interference, interference fringe as holographic cell according to
Secondary exposure recorded on holographic dry plate.
Although the interference fringe generating mode of both the above hologram type method is different, electricity will be used in print procedure
Dynamic displacement platform, by the control action of computer, or to being exposed based on the holographic cell pointwise for calculating hologram fringe, or to being based on
The holographic cell pointwise exposure of anaglyph interference fringe.Electricity driving displacement platform relies primarily on worm drive principle work, and worm screw passes
Dynamic is a kind of mode that control two between centers staggeredly transmit motion and power, by the rotary motion of motor, is converted into rectilinear direction
Motion.However, due to the gap of gear rotation, two gears simultaneously can not possibly be fully engaged against, and relative motion mechanical part it
Between gap certainly exist, so inherently producing idle running error in motion process repeatedly.If do not entered to idle running error
Row amendment, during hologram type, there will necessarily be overlapping or alternating share between adjacent holographic cell, either based on the holographic bar of calculating
The write-through laser printing of line, the synthetic hologram for being also based on anaglyph is printed, and the holographic cell of non-good splicing is inherently
Affect the reproduction effects of final hologram.
Patent CN103486239A proposes the control method and system of a kind of elimination influence of transmission gear gap, patent
CN102003518A propose it is a kind of can eliminate gear engagement between idle running error resislient gear, but above method all compared with
For complexity, the printing of holographic cell is not particularly suited for.
To obtain good holographic cell splicing effect, the quality reproduction of hologram is improved, the present invention proposes holographic single
The idle running error removing method that unit prints.
The content of the invention

The size of unit；
C. displacement platform playbacks in the horizontal direction to its optoelectronic switch zero-bit, further along zero direction more walk a certain step-length；
D. displacement platform playbacks again to optoelectronic switch zero-bit in the horizontal direction, and moves to first holography along zero direction
At the horizontal direction position of unit, proceed the pointwise exposure of the row holographic cell；
E. the process of repeat step B～step D, completes the exposure of pointwise line by line of holographic cell.
It is for second that the serpentine of displacement platform is walked on stage mode, step is：
A. the pointwise exposure of the first row holographic cell is carried out first, and displacement platform moving step sizes in the horizontal direction are equal to complete
The size of interest statement unit；
B. after holographic cell row end exposure, displacement platform line down, the moving step sizes of vertical direction are equal to holographic list
The size of unit；
C. as compensation, displacement platform moves in the horizontal direction the step-length equal with idle running error, moving direction with it is previous
The direction of motion of row displacement platform along this direction conversely, and proceed the pointwise exposure of holographic cell；
