It has become very useful and popular with the avent of laser light. A hologram, which has the property of recording the square of complex amplitude of light wave, is very important from the experimental point of view as a material on interferomentry techniques. The purpose of this paper is to visualize the aspects of density change of an inert gas filled incandescent lamp by using a double exposure technique, i. e., holographic interferometry. It is to estimate the temperature change within the incandescent lamp or on the surface of a valve from a variety of fringe patterns which are reconstructed from the hologram. 7 KJ00001511983 論文 Article departmental bulletin paper 1992 application/pdf 東京工芸大学工学部紀要 1 15 81 87 The Academic Reports, the Faculty of Engineering, Tokyo Polytechnic University AN00159741 03876055 https://kougei.repo.nii.ac.jp/record/208/files/KJ00001511983.pdf https://kougei.repo.nii.ac.jp/records/208 jpn
