9780267680931: Experiments With the Displacement Interferometer (Classic Reprint)

Synopsis

Explore the practical physics of displacement interferometry and how it measures tiny motions with real, hands‑on experiments.

This edition presents a sequence of methods and observations that apply the displacement interferometer to a horizontal pendulum, including direct differential reflection and related optical techniques. Readers will see how careful instrument design, light sources, and high‑quality optics come together to track angular changes and line up precise measurements, even when light conditions or mounting issues challenge accuracy. The narrative also surveys auxiliary experiments and practical notes that illuminate the method’s strengths and its limits in real lab settings.

Structured to show both the setup and the results, the book emphasizes how a well‑built interferometer can reveal subtle shifts in position and tilt. It discusses apparatus choices, calibration ideas, and the interpretation of data from repeated observations, as well as the influence of mechanical and electrical factors on measurement stability. The results illustrate how the method can be extended to related measuring tasks, including applications that bridge optics, mechanics, and instrumentation.

  • How to configure and align a displacement interferometer for direct differential reflection
  • How light quality, mirror surfaces, and pendulum dynamics affect precision
  • How to read and interpret interferometric signals from real experiments
  • How subsequent setups explore broader applications, including electrometer connections

Ideal for readers of early‑20th‑century experimental physics and anyone curious about precision optical measurements in practice.
