<P>PROBLEM TO BE SOLVED: To provide a device and a method characterized by higher measuring speed and a wider measuring field compared with a known apparatus and the method regarding the field of OCT. <P>SOLUTION: The device for determining geometric quantity at least from a first field (MB1) and the geometric quantity from a second field (MB2), distant from the first field (MB1), of a transparent object or a diffusing object includes the coherence tomographic apparatus having an object arm, a reference arm, a detector arm, and a light source (ALQ) emitting light. The device has a first path having the first light path length and a second path having the second light path length formed by the object arm and/or the reference arm, and the light emitted by the light source (ALQ) can be propagated through the first path and the second path. <P>COPYRIGHT: (C)2012,JPO&INPIT |
