Abstract
The utility model discloses a combined Michelson interferometer, which has a basal seat, wherein, a small hole screen, a spectroscopic plate, a compensating plate, and a fixed mirror are orderly arranged on an optical axis which is parallel to the basal plane of the basal seat on one side of the basal seat; a miniature shifter is arranged on a vertical optical axis on the other side of the basal seat; a shifting mirror is fixed on the miniature shifter; the shifting amount of the shifting mirror is 0 to 15 mm. The utility model has the advantages of low cost, simple structure, miniaturization, convenient operation, and visible optical path, and the utility model can be used for replacing the function of the traditional Michelson interferometer.
Description
The utility model relates to interferometer, relates in particular to the assembly unit Michelson interferometer.
Michelson interferometer almost is the blank of all kinds of metering interferometers in modern age, do to also have many-sided purposes after change or the expansion on its basis slightly, as vibration measuring, collimation, survey surface smoothness, deformation, displacement, do not lose its ample scope for abilities in fields such as holographic and spectral analyses yet.As can on the moving lens of Michelson interference system, scanning by bonding piezoelectric ceramics; As with two catoptrons of Michelson interferometer with two diffusion planes replace diffused light interferometer etc.
The purpose of this utility model provides assembly unit Michelson interferometer a kind of simple for structure, easy to use.
The utility model is taked following measures in order to achieve the above object, it has pedestal, on the pedestal one side optical axis parallel, be provided with aperture screen, beam-splitter, compensating plate, fixed mirror successively with the basal plane of pedestal, on the vertical optical axis of pedestal opposite side, be provided with miniature shifter, on miniature shifter, be fixed with moving lens.
The utility model has the advantages that: cost is low, simple for structure, the function of miniaturization, easy to use, alternative traditional Michelson interferometer.
Do the detail explanation below in conjunction with accompanying drawing
Accompanying drawing is an assembly unit Michelson interferometer synoptic diagram.
The assembly unit Michelson interferometer has pedestal, on the pedestal one side optical axis parallel, be provided with aperture screen 1, beam-splitter 2, compensating plate 3, fixed mirror 4 successively with the basal plane of pedestal, on the vertical optical axis of pedestal opposite side, be provided with miniature shifter 6, on miniature shifter, be fixed with moving lens 5, use laser, white light and other monochromatic sources.The effect of setting up aperture screen 1 has two, and the first produces accurate equal inclination fringes; It two helps regulating.After the removal screen is changed parallel beam, can produce equal thickness fringes.Miniature amount of movement is 0～15 millimeter, is enough to finish before and after zero light path the function of signal Processing.
Using method of the present utility model is:
1. regulating laser instrument and instrument optical axis goes the same way contour;
2. put into the aperture screen, make laser pass through aperture;
3. transfer fixed mirror and index glass frame, each road reflected light is put on the perforation hole of aperture screen altogether;
4. move into beam expanding lens (disperse or parallel);
5. on screen, observe interference fringe, regulate the amount of movement of shifter, (uniform thickness) striped that inclines such as just can observe;
6. when transferring to zero light path, change white light into and can obtain satisfied white light fringe.
