Abstract
A Michelson isocline interference magnetic centering device mainly comprises magnets and an adjusting screw, wherein the static magnet is fixed on a horizontal glass cross bar of a Michelson interferometer, the dynamic magnet is fixed on the adjusting screw, a group of dynamic magnet and static magnet is respectively arranged in each of the horizontal and vertical directions, the same poles of each group of dynamic magnet and static magnet are opposite, a repulsive force is formed between the dynamic magnet and the static magnet, moderate bending of the horizontal glass cross bar is formed under the action of the repulsive force between the dynamic magnet and the static magnet, the bending degree of the horizontal glass cross bar is changed along with the size of the repulsive force just by adjusting the clearance between the dynamic magnet and the static magnet to drive a horizontal glass surface to swing to achieve the adjusting effect for an isocline interference circle center position; and the device has the advantage that the centering range can be determined by an operator, and therefore, the defect that the traditional pull rod screw has small adjusting range is overcome, and particularly the risks of losing the centering effect and causing interference image loss are avoided.
Description
Technical field
The present invention is applied to the home position of Michelson interference image and regulates.
Background technology
Michelson equal inclination interference image is concentric circles, and fine setting Michelson equal inclination interference image home position relies on level and vertical two pull bar screws.The pull bar screw mainly is made up of inner bolt, screw bolt seat and swivel nut, and its shortcoming is that the aligning scope is less, usually is that screw has been transferred to extreme position; The center of circle of interference image is not also regulated and is put in place; Particularly experimental implementation person often the swivel nut screw bolt seat of having back-outed, loses the aligning effect, even causes existing interference image to disappear; Wanting to twist back initial position to swivel nut again also need can not free-handly accomplish by instrument.The difficulty of existing pull bar screw existence in fine setting Michelson equal inclination interference home position is regulated that Here it is.
Summary of the invention
In order to overcome the difficulty that existing pull bar screw exists when finely tuning Michelson equal inclination interference home position, the present invention has designed a kind of Michelson equal inclination interference magnetic force aligning device.
Michelson equal inclination interference magnetic force aligning device mainly is made up of magnetic patch and set screw, and on the horizontal glass cross bar that magnetostatic is fixed on Michelson interferometer, moving magnetic patch is fixed on the set screw, and one group of dynamic and static magnetic patch is respectively arranged in the horizontal and vertical directions; The homopolarity of each group magnetic patch is relative, produces repulsion between the sound magnetic patch, between the sound magnetic patch, draws a balanced line; When testing beginning, that regulates moving magnetic patch exposes end face to the balanced line position, and the repulsion between the sound magnetic patch makes the generation of horizontal glass cross bar an amount of crooked at this moment; When needs are regulated the equal inclination interference home position, as long as gap length is just passable between the adjusting sound magnetic patch, gap smaller; Repulsion increases, and it is big that the gap becomes, and repulsion reduces; The degree of crook of horizontal glass cross bar drives the swing of horizontal glass face along with the repulsion size variation, plays the regulating action of equal inclination interference home position; After experiment finishes, regulate distance maximum between the sound magnetic patch, make the degree of crook of horizontal glass cross bar minimum.
Advantage of the present invention is that the aligning range size can be determined by the operator; Moving magnetic patch is crossed balanced line and is made sound magnetic patch spacing little during beginning; The aligning scope is just big; Otherwise just little, this has just overcome the little shortcoming of existing pull bar screw adjusted scope, the danger of particularly having avoided forfeiture aligning effect and having caused interference image to disappear.
