AI Technical Summary

Problems solved by technology

In the experiment, if the two plane mirrors are not perpendicular, the interference fringes may be deformed or even the interference fringes cannot be seen at all, so that subsequent experiments such as light wave wavelength measurement cannot be carried out.

Abstract

The invention discloses a Michelson interferometer convenient to adjust. The Michelson interferometer comprises a beam splitting plate, a compensating plate, a first plane reflector, a second plane reflector and an observing screen, and further comprises an inversed-L-shaped support and a support base. The inversed-L-shaped support comprises a first support wall and a second support wall which are perpendicular to each other. The first plane reflector and the second plane reflector are attached to the surface of the first support wall and the surface of the second support wall respectively. The Michelson interferometer can replace a traditional Michelson interferometer to be used for observing and measuring the interference phenomenon, great convenience is brought to adjustment on the Michelson interferometer, and the experiment efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the field of physical experiment instruments, and relates to an optical experiment instrument, in particular to a conveniently adjustable Michelson interferometer. Background technique [0002] The Michelson interferometer is a commonly used optical experimental instrument. The Michelson interferometer includes two independently arranged plane mirrors, two parallel beam splitters and compensation plates, and an observation screen for receiving interference patterns. The beam splitter and the compensation plate form an angle of 45 degrees with the two plane mirrors respectively. The beam splitter divides the incident light into two beams, which are directed to two plane mirrors and interfered after being reflected by the plane mirrors. The compensation plate plays the role of compensating the optical path of the optical path, which is used to make the optical path of the two coherent beams in the glass medium equal. The diffi...
