A method of analysing out of plane deflections in materials under load utilising the projection of a reference grating on to such a material whilst recording information relating to the individual color channels of a color video recording camera thereby providing an imaginery reference grating allowing a conventional Moire fringe analysis of the material.

Non-contact deformation measurement

Apparatus for the measurement of out of plane displacements of a panel of material under test comprises; a laser (2) capable of focusing a laser spot (8) onto the surface of the panel (6) of material; a line generating lens (12) for converting the image of the projected laser spot (8) into a focused line (22); and, a photo diode (16) responsive to illumination by laser light and so orientated and disposed in relation to the generated laser line (22) that the out of plane distortions of the panel (16) and resulting movement of the spot (8 to 8') produce a corresponding translation of the generated line (18) across the face of the photo diode (16) and the photo diode (16) produces a recordable output proportional to the out of plane deflection of the panel (6).
