Abstract: Transmission fringes in reflection multiple-beam interferometry are obtained independently of the characteristics of the coating of the reference surface by coupling a two-beam interferometer to the multiple-beam interferometer.The two-beam interferometer is defined by the reference surface of the multiple-beam interferometer and one additional mirror in a Twyman configuration.

TL;DR: The use of interferometry for heat transfer studies enables a complete field of view to be quantitatively examined at one time without disturbing the temperature distribution being measured as discussed by the authors, which is a technique that has been shown to be effective in heat transfer applications.

TL;DR: In this paper, a Mach Zehnder interferometer is used for electron line density measurements of a rapidly varying plasma, where fringe detections are made with a system of two photo-multipliers.
Abstract: A Mach Zehnder interferometer is described which is used for electron line density measurements of a rapidly varying plasma. Fringe detections is made with a system of two photo-multipliers which allows one to follow the sense of variation of the electron line density in an unambiguous manner. The sensitivity of the device (approximately 0.01 fringe) allows precise measurements to be made in experimental situations where electron line density variations produce only fractions of a fringe shift. This interferometer is used to measure the electron line density of an axial current discharge in 25 mtorr H2. The density profile of the plasma is obtained by scanning a 3 mm wide He-Ne laser beam across the diameter of the discharge tube. Complete ionisation of the gas is found after 9 μsec.

Abstract: マッハ・ツェンダー (M・Z) 干渉計は屈折事場を干渉縞の移動数としてとらえるものであるが, これを用いて焔内部の温度の分布を実測することを試みた。これの定量化にあたっては, a) 干渉縞の移動数から屈折率分布が光路に沿った積分値でえられる。b) 屈折率場は温度場と濃度場の両方によって影響を受ける, などの問題点があった。ここでは, 軸対称な水素焔を用いて上記の問題点を解決し, 測定値を理論最高焔温度および熱電対による測定値と比較検討した結果, M・Z干渉計を用いて焔の温度分布を比絞的精度よく測定できることが判明した。
