heal.abstract	The optical method of pseudocaustics consists of directing a light beam on a plane specimen and obtaining enlarged the deformed shape of its boundary on a screen after the reflection and/or refraction of this beam on the specimen. In case of plane isotropic elastic media, the pseudocaustics can be used to get the derivative F{cyrillic}'(z) of the complex potential F{cyrillic}(z) of Muskhelishvili. In this paper this property of pseudocaustics was used for the experimental determination of both complex potentials F{cyrillic}(z) and Ψ(z) in the whole specimen for both cases of the first and the second fundamental problems of plane elasticity. This can be achieved by one simple experiment and very little computational effort, not comprising the solution of any kind of equations. The proposed method was applied to the problem of an infinite elastic medium under tension with a circular hole. The experimental results obtained are in good agreement with the corresponding theoretical results. © 1981.	en
