Principal mechanism. A coherent light beam is divided by a central beam splitter into two orthogonal paths. Suspended end mirrors reflect the beams, which recombine at the readout photodetector. Differential displacement changes the relative phase and detected intensity.
Physical laws (textbook). In an ideal Michelson geometry, φ = 4πΔx / λ; normalized readout I/I₀ = (1 + V cosφ)/2; propagation round-trip t = 2L/c; free spectral range FSR = c/(2L), with c = 299,792,458 m/s. We use illustrative visibility V = 0.88.
Independent check. FSR = 1 / t, calculated separately from the time readout. This algebraic identity checks implementation consistency, not physical calibration.
Genuine scientific features. Orthogonal arms, a coated beam splitter, suspended end test masses, high vacuum, seismic isolation, coherent source and optical photodetection are physically grounded concepts.
Engineering-inspired reconstruction. Frames, rail spacing, service platforms, pump cartridges and electronic racks are invented arrangements for clear inspection. All geometric lengths are scaled.
Simplified educational representation. This instrument does not solve the full optical fields, servo-loop dynamics, seismic noise or detector sensitivity. The animated rays and moving suspension symbols are illustrative, not validated scientific simulation.
Speculative components. The fictional LUMENIS IX-4 housing, actuator casings and instrument styling are unique concept-design elements without claimed operating tolerances.
