Device for interferometrically analysing the deformations of a body. |
摘要 |
<p>The invention relates to a device comprising the cooperation of two analysis systems operating at different wavelengths. The first system carries out a superposition of a graticule (2) engraved on the surface of a body (1) analysed with an optical graticule (8) and enables the in-plane deformations of the body (1) to be obtained by Moiré fringes. The second system carries out the superposition of an image of an optical graticule (10) projected onto the surface of the body (1) with an optical graticule (8) and enables information on the out-of-plane deformations of the body (1) to be derived by Moiré fringes. <IMAGE></p> |
