Abstract
The utility model discloses an antidetonation type michelson interferometer, including base, guide rail, portable speculum, beam -splitter, compensating plate and stationary mirror, portable speculum passes through the layer board and installs on the guide rail, the layer board is followed under transmission system's control the guide rail parallel translation, its key lies in: the stationary mirror is installed on the mirror holder, and this mirror holder passes through rigid support spare to be fixed on the lateral wall of guide rail for the mirror surface mutually perpendicular of stationary mirror and portable speculum still be provided with two at least adjusting screw on the mirror holder, last coaxial two knobs that are provided with of adjusting screw, wherein, the radius of coarse adjusting knob is less than the radius of finely tuning the knob. Beneficial effect: fine setting knob structure is simpler, does not use the fine setting spring, and fundamentally avoids causing michelson interferometer to adjust the problem of difficulty because of the shake of fine setting spring self.
Description
Technical field
The utility model relates to Michelson interferometer, specifically, is a kind of Anti-seismic Michelson interferometer.
Background technology
Michelson interferometer is modal one in optical interdferometer, and its principle reflects through removable reflective mirror and stationary mirror respectively after a branch of incident light is divided into two bundles, this two-beam thus can interfere.The difficult point of Michelson interferometer adjustment, is the removable reflective mirror of separate setting and stationary mirror will be adjusted to complete plumbness, just can observes the Interference Pattern of Equal Inclination of concentric ring-shaped.
For adjusting the angle of stationary mirror, traditional Michelson interferometer is provided with three mutually in 120 ° of uniform milled screws at stationary mirror mirror holder back, when milled screw is tightened, stationary mirror is pushed up after nail Caudad, stationary mirror generation angle is changed, and three milled screws cooperatively interact and can carry out coarse adjustment to stationary mirror arbitrary angle; In addition, be also provided with two orthogonal fine setting springs, fine setting spring is connected between micrometer adjusting screw and fixation reflex mirror support, is realized the inclination angle of fine setting stationary mirror by the elastic deformation of fine setting spring straining fixation reflex mirror support self.Tradition Michelson interferometer uses the inclination angle of fine setting spring fine setting stationary mirror; but when reality uses; fine setting spring often can be disturbed by the vibrations that people in laboratory causes by walk about, outdoor vehicular traffic etc., thus affects the use of Michelson interferometer.
Utility model content
In view of this, the utility model provides a kind of shockproof Michelson interferometer, fundamentally solves because fine setting spring is subject to external shock and causes Michelson interferometer to regulate the problem of difficulty.
Concrete technical scheme is as follows:
A kind of Anti-seismic Michelson interferometer, comprise base, guide rail, movable mirror, beam-splitter, compensating plate and stationary mirror, described movable mirror is arranged on described guide rail by supporting plate, described supporting plate moves along described guide rail parallel under the control of kinematic train, its key is: described stationary mirror is arranged on mirror holder, this mirror holder is fixed on the sidewall of described guide rail by rigid strutting piece, make stationary mirror mutually vertical with the minute surface of movable mirror, described mirror holder is also provided with at least two set screw, described set screw is coaxially arranged with two knobs, wherein, the radius of coarse adjustment knob is less than the radius of vernier adjustment knob.
Based on the Michelson interferometer of said structure, traditional coarse adjustment knob structure adds coaxial vernier adjustment knob, the function of fine setting is realized by strengthening coarse adjustment knob radius, do not use fine setting spring, fundamentally avoid because the shake of fine setting spring self causes Michelson interferometer to regulate the problem of difficulty.
Further, described set screw is provided with two, and for regulating the angle of pitch and the inclination angle, left and right of described stationary mirror, the kernel of section connecting line of described two set screw and horizontal line are in ± 45 ° of angles; In addition, three described set screw also can be set, and be evenly distributed on the back side of described stationary mirror, realize the angle of pitch to described stationary mirror and left and right tilt adjustment.
In the specific implementation, described rigid strutting piece is inverted L shape, is fixed by screws on the sidewall of described guide rail; In addition, the bottom of described base is provided with leveling serew, and described leveling serew is also provided with crash roll.
Beneficial effect: vernier adjustment knob structure is more simple, does not use fine setting spring, fundamentally avoids because the shake of fine setting spring self causes Michelson interferometer to regulate the problem of difficulty.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
A kind of Anti-seismic Michelson interferometer as shown in Figure 1, comprise base 1, guide rail 2, movable mirror 3, beam-splitter 4, compensating plate 5 and stationary mirror 6, described movable mirror 3 is arranged on described guide rail 2 by supporting plate 7, described supporting plate 7 moves in parallel along described guide rail 2 under the control of kinematic train 8, its key is: described stationary mirror 6 is arranged on mirror holder 9, this mirror holder 9 is fixed on the sidewall of described guide rail 2 by rigid strutting piece 10, make stationary mirror 6 mutually vertical with the minute surface of movable mirror 3, described mirror holder 9 is also provided with two set screw 11, wherein, the radius of coarse adjustment knob 12 is less than the radius of vernier adjustment knob 13.
In the present embodiment, two set screw 11 kernel of section connecting lines and horizontal line are 45 ° of angles.
Based on the Michelson interferometer of said structure, the structure of traditional coarse adjustment knob 12 adds coaxial vernier adjustment knob 13, the function of fine setting is realized by strengthening coarse adjustment knob 12 radius, do not use fine setting spring, fundamentally avoid because the shake of fine setting spring self causes Michelson interferometer to regulate the problem of difficulty.
In the present embodiment, described rigid strutting piece 10, in inverted L shape, is fixed by screws on the sidewall of described guide rail 2; In addition, be it can also be seen that by Fig. 1, the bottom of described base 1 is provided with leveling serew 14, and described leveling serew 14 is also provided with crash roll 15, eliminates further because desktop shakes the interference brought to Michelson interferometer.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
