Abstract: In a method for detecting the deformation of objects (1), a sequence of pictures of the object (1) is taken with a measurement method during the deformation of the object (1).

To improve such method, there is formed the difference between the current phase image or the respective current phase image and the phase image of an initial state. This difference or these differences is/are evaluated and/or displayed on a visual display unit and/or stored.

Abstract: The invention serves for the contour measurement and/or deformation measurement of an object, particularly a tire or a structural component of a composite material. The object is irradiated with light, particularly structured light, that is emitted by a radiation source and consists, in particular, of coherent light or partially coherent light, especially laser light.

Abstract: A method serves the direct phase-angle measurement of radiation, in particular of light radiation which is reflected from a body. The body is exposed to coherent radiation. The radiation reflected from the body is imaged by an imaging optical system (6) in an image plane in which a sensor is located. A reference radiation generated in accordance with the shearing method is superimposed on the sensor. The phase of the radiation from the body is determined from the measurement signals of the sensor. To improve such a method, the imaging optical system (6) possesses a diaphragm (11) having one or two apertures (12, 13) (FIG. 2a).
