Abstract
A kind of device accurately adjusting optical path difference and its angle for Michelson's interferometer is related to the adjusting of Michelson's interferometer optical path difference and its angle.To overcome the problems such as adjusting optical path difference in Michelson interference experiment and the light path angle time is long, error is big, a device that can accurately adjust optical path difference and its light path angle is devised.The technical scheme is that：The adjusting optical path difference of design and its device of light path angle are made of guide rail and sliding block, and guide rail is made of two aluminium alloy columns, is made marks on the both sides of aluminium alloy column, form millimeter graduated scale；There are one screw thread holes at the center of two aluminium alloy columns, and two aluminium alloy columns are in the state of exact vertical, are used in combination screw to pass through the screw thread hole of two aluminium alloy columns, while being fixed with nut, ensure that two aluminium alloy columns are constantly in exact vertical state.One cavity of envisaged underneath of sliding block, sliding block can just pass through aluminium alloy column.Using this device, can be very good to solve these problems.
Description
Technical field
The present invention relates to physics facility fields, the more particularly to tune of Michelson's interferometer optical path difference and its angle
Section.
Background technology
In Experiment of College Physics room, Michelson's interferometer is that a kind of very accurate observation and measuring instrument, application are non-
Often extensively, such as the measurement of liquid refractivity, the measurement of air refraction under different pressure, the measurement of optical source wavelength.In light
It is the most key in order to observe the good equal inclination interference annulus pattern of effect when building michelson interferometer optical path on platform
Two links are：It needs two optical path adjustings to be exact vertical, while optical path difference is also adjusted to 0, at present optical path difference
It is the position for utilizing tape measure repeated measurement or mobile mirror to adjust all, until there is a phenomenon where 0 optical path difference, angle
The adjusting of degree is obtained by observation experiment phenomenon with feeling, and there are one quantitative measurement standards.Such adjusting
Method efficiency is low, and error is big.
Invention content
The present invention is to overcome to adjust optical path difference in Michelson interference experiment and the light path angle time is long, error is big etc. asks
Topic, devises a device that can accurately adjust optical path difference and its light path angle, can be very good to solve these problems.
The present invention solve its technical problem the technical solution adopted is that：One kind accurately adjusting light for Michelson's interferometer
The device of path difference and its angle, is made of guide rail and sliding block, it is characterized in that：Guide rail is made of two aluminium alloy square columns, aluminium alloy
The length of column is 25cm, width 2cm, thickness are 0.5cm, is made marks on the both sides of aluminium alloy column, and millimeter scale is formed
Ruler；There are one screw thread holes at the center of two aluminium alloy columns, and two aluminium alloy columns are in the state of exact vertical, screw is used in combination
It across the screw thread hole of two aluminium alloy columns, while being fixed with nut, ensures that two aluminium alloy columns are constantly in exact vertical state.
One height of envisaged underneath of original sliding block be 0.5cm, the cavity that width is 2cm, enable aluminum alloy to column just can pass through slide
Block.Guide rail is placed on optical table, then by sliding block through on guide rail, because two aluminium alloy columns are vertical, at two
The light built on aluminium alloy column is also just vertical.When experiment, on the basis of the millimeter graduation mark on guide rail, it is moved forward and backward on guide rail
Sliding block, so that it may optical path difference is accurately adjusted to 0.And then experimental period is saved, improve experimental precision.
The beneficial effects of the invention are as follows:Instrument change is fewer, and improvement cost is low, and can save experimental period, reduces real
Test error.
Description of the drawings
The invention will be further described below in conjunction with the accompanying drawings.

Wherein 1, guide rail, 2, metal alloy column, 3, millimeter graduated scale, 4, screw thread hole, 5, sliding block, 6, cavity.
Specific implementation mode
Guide rail 1 is made of two aluminium alloy columns 2, and the length of aluminium alloy column 2 is 25cm, width 2cm, thickness 0.5cm
, it makes marks on the both sides of aluminium alloy column 2, forms millimeter graduated scale 3；There are one screw threads at the center of two aluminium alloy columns 2
Two aluminium alloy columns 2 are in the state of exact vertical by hole 4, are used in combination screw to pass through the screw thread hole 4 of two aluminium alloy columns 2, simultaneously
It is fixed with nut, ensures that two aluminium alloy columns 2 are constantly in exact vertical state.One height of envisaged underneath of sliding block 5 is
0.5cm, the cavity 6 that width is 2cm, sliding block 6 can just pass through aluminum alloy sheet 2.
