Embodiment
In the drawings and in which, the parts that identical or function is identical and light are provided with identical Reference numeral.In addition, cartesian coordinate system is depicted in some drawings, so that determine direction.
Carrier 1 can be seen by Fig. 1 and 2, that described carrier structure becomes tabular and can deflection device be used as.Described carrier 1 has structurized optical function interface 2 on the side in its front in the drawings.The back side of carrier is smooth surface 3 in the embodiment shown.
On interface 2, be arranged side by side in X direction multiple only draw in fig. 2 for illustration of object point surperficial 2a, 2b, 2c ..., 2p, 2o, wherein, described point of surperficial 2a, 2b, 2c ..., each in 2m, 2p, 2o be the surface reversed and have certain similarity with the surface of screw propeller (blade).Each point of surperficial 2a, 2b, 2c ..., 2m, 2p, 2o proceed to each other without transition part and form wheel chair access continuous print interface 2 (see Fig. 1) together.
A point surperficial 2c such as in the right side edge in fig. 2 at interface 2 has convex curvature, described curvature diminish when Y-direction is advanced on interface 2 and interface 2 in convex 2 on the left of edge on transition be recessed curvature.Correspondingly, point surperficial 2m in the right side edge in fig. 2 at interface 2 has recessed curvature, described curvature diminish when Y-direction is advanced on interface 2 and interface 2 in convex 2 on the left of edge on transition be recessed curvature.When advancing along Y-direction on interface 2 here, curvature is consecutive variations correspondingly.
In addition, divide surperficial 2a, 2b, 2c ..., 2p, 2o be arranged side by side in X direction like this, makes the same consecutive variations of described curvature when advancing in X direction on interface 2.Such as when advancing from point surperficial 2a along negative X-direction on the edge on the right side in fig. 2 at interface 2, convex curvature increases, until roughly reach maximum curvature in the region of point surperficial 2c.Then, described convex curvature reduces and transfers recessed curvature to.This recessed curvature transfers a convex curvature to, and this convex curvature roughly transfers recessed curvature to again in the region of interface 2m.
Now, in X direction or when advancing on interface 2 along negative X-direction, be not only curvature in X direction, and all change along the curvature of Y-direction.This means, when advancing in X direction, through the light at interface 2 along the deflection of Y-direction generation varying strength.There is such possibility, there is such region, in this region, when advancing in X direction in the central authorities namely between the right side edge at optical function interface in fig. 1 and 2 and left side edge, only along the Curvature varying of Y-direction, and curvature does not in X direction change.
Completely it is possible that being arranged side by side than shown point surface is in X direction many or few point surface.Particularly can arrange on interface 2 than the how recessed and convex region shown in Fig. 1 and Fig. 2.
What illustrate in figs. 3 and 4 comprises according to the carrier 1 of Fig. 1 and Fig. 2 and the focus device 4 of distortion of cylindrical lens being configured to plano-convex according to the first form of implementation of device of the present invention, and described focus device is arranged on before carrier 1 along the propagation direction of light 5.Here the direction of propagation of light 5 corresponds essentially to Z-direction.In addition, the cylindrical lens of the focus device 4 of distortion is directed like this, and its mast axis is extended along Y-direction.
The light 5 deflected can be laser beam especially.
In addition, there is such possibility, that is, the cylindrical lens substituting plano-convex can also use the cylindrical lens of biconvex or convex-concave.Alternatively or additionally, also there is such possibility, that is, substitute a cylindrical lens and multiple cylindrical lens is set.
In the embodiment shown, the optical function interface 2 of carrier 1 thus serves as the plane of incidence towards light 5.Therefore, light 5 is penetrated from carrier 1 by smooth surface 3.But completely also there is such possibility, that is, carrier 1 is arranged in said device like this, make smooth surface 3 be used as the plane of incidence, and optical function interface 2 is used as outgoing plane.
There is such possibility in addition, that is, the surface 2 of optical function is set to the plane of incidence and outgoing plane.
The focus device 4 of distortion makes light 5 only focus on optical function interface 2 about X-direction, and phase Reflect light line 5 passes through unaffected the focus device 4 of distortion about Y-direction.Thus, optical function interface 2 obtains focal line, described focal line extends along Y-direction and has very little size in X direction, such as, in the size of μm scope.
In order to make light deflection, carrier moves in X direction or along negative X-direction.Now, due to the configuration at optical function interface 2, light deflects along Y-direction with X-coordinate varying strength respectively.Here can set, will be the projected area of light 5 about the regional choice in the middle of Y-direction, the feature in described region be, when light 5 moves in X direction, deflection only along Y-direction changes, on the contrary, light 5 about X-direction substantially do not deflect by carrier 1.
In other words there is such possibility, that is, the deflection of light 5 is carried out substantially or only in Y-Z plane.
In other words, by carrier 1 particularly continuous print motion in X direction, the light 5 of injection can the enterprising line scanning at prespecified angular range.By be arranged side by side on interface 2 in X direction multiple torsion divide surperficial 2a, 2b, 2c ..., 2p, 2o, realize the to-and-fro movement of light 5 here along Y-direction.Alternatively, such as can realize the to-and-fro movement of light 5 like this when only having a torsional surface, that is, carrier 1 is such as moved back and forth by vibratory movement.
Due to the extension that the projected area of light on interface 2 is very little in X direction, when carrier 1 correspondingly has larger speed in X direction, changing very fast and realizing switching time short as far as possible between each separated point in long distance field thus along Y-direction deflection can be realized.Simultaneously by the projected area of light on interface 2 along the larger extension of Y-direction, high resolving power can be realized, the separated point of high quantity in other words in the long distance field of the light 5 of injection.That light xsect is about 10mm along Y-direction on interface 2, and light xsect is about 10 μm in X direction on interface 2 for one of described projected area common example.
There is such possibility, namely carrier 1 is not transparent, but is designed to reflexive, thus the light 5 focused on interface 2 is not refraction, but is reflected.The light of injection now such as can be separated by polariscope and incident light 5.

Fig. 7 to Fig. 9 illustrates an embodiment according to device of the present invention, and wherein, carrier 1 is configured with the discoid pieces of circular circumference.Interface 2 by Fig. 2 illustrate point surperficial 2a, a 2b, 2c ..., 2p, 2o being circumferentially arranged side by side on the carrier 1 at this circle, thus the rotation of discoid pieces is equivalent to the carrier motion in X direction of Fig. 3 and Fig. 4.
Carrier 1 according to Fig. 7 to Fig. 9 can rotate around the axis 8 of described circle, as illustrated by the arrow 9 in Fig. 7 and Fig. 8.Therefore the circumferencial direction corresponding to X-direction is relevant to the position angle φ that carrier 1 rotates through.
