YGS-2 Portable Michelson Demonstrator / Equal Inclination and Equal Thickness Interference Demonstrator
The Michelson interferometer is a crucial instrument in physics—it not only confirmed Einstein’s postulate of the constancy of the speed of light, but also demonstrated that light can propagate and exhibit interference without requiring a medium—meaning that the so-called "ether," once thought to permeate space, does not exist. Yet, this groundbreaking discovery simultaneously gave rise to a lingering puzzle in physics (often referred to as "a single dark cloud"): if there’s no ether—no medium—how exactly does light travel? And more specifically, how does light produce interference in the first place? As Albert Einstein once remarked, "I’ve always regarded Michelson as an artist among scientists; his greatest joy seemed to stem from the sheer elegance of the experiment itself and the masterful precision of the methods he employed." To scientists, the Michelson interferometer is not just a scientific tool—it’s also a remarkable work of art. For both functionality and aesthetic appeal, the LGS-2 portable Michelson product comes encased in a sleek, transparent acrylic display box, offering dual protection: it shields the instrument from dust while transforming it into a captivating piece of art. After all, this device aims to balance practical utility with artistic value.

YGS-2 Portable Michelson Demonstrator / Equal Inclination and Equal Thickness Interference Demonstrator
The Michelson interferometer is a crucial instrument in physics, having provided definitive evidence supporting Einstein’s postulate of the constancy of the speed of light—and demonstrating that light can propagate and exhibit interference without requiring a medium, thus disproving the existence of the hypothetical "ether" permeating space. Yet, this groundbreaking discovery also gave rise to a lingering puzzle in physics (often referred to as "a single dark cloud"): If there’s no ether—no medium—how exactly does light travel? And more specifically, how does light manage to interfere with itself under such conditions? As Albert Einstein once remarked, "I’ve always regarded Michelson as an artist among scientists; his greatest joy seemed to stem from the sheer elegance of the experiment itself and the exquisite precision of the methods he employed." To scientists, the Michelson interferometer is not only a cutting-edge scientific tool but also a masterpiece of engineering artistry. For both functionality and aesthetic appeal, the LGS-2 portable Michelson product comes encased in a sleek, transparent acrylic display box—designed not only to protect the device from dust but also to showcase it as a captivating work of art. After all, this instrument strives to balance practical utility with profound artistic value.
Experimental Principle:
1. The Structure of the Michelson Interferometer
The Michelson interferometer consists primarily of a beam splitter, a compensating plate, a fixed mirror, a movable mirror, and an adjustment mechanism. A laser beam is split into two beams by the beam splitter—one beam is reflected by the fixed mirror, while the other is reflected by the movable mirror. These two reflected beams then recombine at the beam splitter, creating an interference pattern.
2. Principle of Equal-Inclination Interference
When the two mirrors are positioned strictly perpendicular to each other, equi-inclination interference fringes are formed. In this case, for light rays with the same angle of incidence, their optical path differences are identical, resulting in concentric circular fringes. The optical path difference ΔL is given by ΔL = 2d cosθ, where d is the equivalent air-gap thickness between the two mirrors, and θ is the angle of incidence. As the value of d changes, the interference fringes shift accordingly. Specifically, the change in optical path difference at the center, ΔL, is directly related to the distance Δd by which the mirror is moved: ΔL = 2Δd = mλ (where m represents the number of fringe shifts, and λ is the wavelength of the light). This relationship allows us to accurately measure the wavelength of the light.
3. Principle of Equal Thickness Interference
When the two mirrors are not perfectly perpendicular, they produce equal-thickness interference fringes, which appear as equidistant straight lines running parallel to the intersection line of the two mirrors. Near the intersection of the mirrors, the optical path difference can be approximated as ΔL = 2d cosθ ≈ 2d (when θ is very small). In this case, the interference fringes directly reflect the variations in the thickness of the air film.

A quantum computer is a machine capable of performing quantum computing, leveraging the principles of quantum mechanics to carry out mathematical and logical operations, as well as process and store information. Theoretically, it is a physical system that uses quantum bits (qubits) as its fundamental storage units, with quantum dynamical evolution forming the basis for information computation. Currently, the main technological approaches can be categorized into six types: superconducting, ion-trap, photonic quantum, neutral atoms, silicon spin, and topological.
