摘要 |
<p>Arrangement for the contactless and artificial determination of the two- or three-dimensional shape of an object (1) by illuminating the object with a light source (2) produced from two coherent illumination points which are separated from each other. As a result primary real interference patterns are produced in the direction of the light beams (5b). The object (1) is observed by means of a primary imaginary interference pattern obtained via two simultaneously-connected coherent observation points (3) which are separated from each other. The combination of the two interference patterns gives a secondary pattern of Moiré lines which provides an artificial image (4) which is significant for the shape of the object.</p> |
