Optical holography known as a kind of wavefront reconstruction technique was discovered by Dennis Gabor in 1947, in connection with three-dimensional viewing of x-ray images. 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.
