| 摘要 |
The invention relates to a device (10) for measuring the dimensions of a body (13), with radiating means (19) which give off a radiation in the direction of the body (13), whereby the body (13) and the device (10) may be moved relative to each other along an axis (40) of the device, means for aligning the radiation given out by the radiating means approximately parallel, in a second plane (E2) perpendicular to the axis (40), a shutter device (28, 29), arranged in the aligned beam path, such as to mask a part of the aligned radiation, whereby only a remaining portion of the radiation illuminates the body (13) and forms a sharp light edge (L) on a surface of the body, at least one sensor device (15) and at least one optical device which guides reflected radiation from the light edge (L) in a first plane (E1), inclined to the axis (40), in the direction of the sensor device and an analytical unit for dimension determination of the body, electrically connected to the sensor device (15). |
