Fundamentals of Holography and Interferometryer to use, but is also much easier and convenient to handle. With holographic interferometry there is no need to machine or manufacture windows for test sections, mirrors and lenses of the optical components with special precision or accuracy, because imperfections are automatically balanced by the holographic two-step procedure.corpus-callosum 发表于 2025-3-28 19:05:58

Differential Interferometryia. Interferometry represents a major part among a variety of techniques. It uses the interference of two wavefronts of light propagating to the recording plane via two different optical paths — passing through or passing by the test substance. Presupposition for interference is the optical coherence of the two conjugate wavefronts.虚度 发表于 2025-3-29 19:27:55

Laser-Doppler Velocimetry (LDV)n more detail it should be noted that in a modified version the same technique can be applied to velocity measurements of surfaces of solids. In comparison to traditional flow measurement techniques, e.g., the hot wire anemometer or Prandtl probe, the LDV provides the following advantages:永久 发表于 2025-3-29 23:58:04
