Paper Abstract

The article is dealing with the measurement of three-dimensional shapes of objects. Such measurement is called the topography. The one of moire methods — the projection moire topography —is used. For improvement of measurement quality some methods are introduced. At first it is the washing-up method which deletes the linear background. At second the fringe-shifting method is described used for increasing of data quantity. And finally the optical/digital fringe multiplication is mentioned as a method for increasing the accuracy ofmeasurement. The topography is illustrated on the example ofmeasurement ofpump blade including its theory, experimental set-up and results.
