"This is a new and perspective trend of real time non-contact measurements of arbitrary shape deformation of surfaces. The principle of the method is based on measurement of the gradient of wave field after its interaction with the tested object. Thetechnique uses new array optical elements, CCD sensors and LC displays with a subsequent automatic computer evaluation. In comparison to optical measurement methods used at present, which do not allow to investigate arbitrary deformations and alsorequire laser as a source of radiation, this method has the advantage of measuring arbitrary deformations, the laser is not required as a source of radiation and it is possible to measure dynamic deformations. It is not possible with commonly usedmeasurement methods. Further purchase costs for the proposed measurement technique are much lower than costs of present interferometric systems. The proposed method can be used for a noncontact measurement of shape deformation of surfaces, e.g. for"@en . . "GP103/03/P001" . "0"^^ . . . . . . .
