    • The invention relates to a method and to a device for optically scanning a sample (1). The device comprises an adjusting unit (2, 3) and a scanning device (4, 5) which comprises an optical unit (4) and a scanning unit (5). The inventive device also comprises a control arrangement (6) which controls the optical unit (4), the scanning unit (5) and the adjusting unit (2, 3). The sample (1) is displaced in relation to the scanning device (4, 5), or vice-versa, by means of the adjusting unit (2, 3) which is impinged upon by the control arrangement (6). As a result, individual images (7), which are obtained by means of the scanning device (4, 5) are assembled to make at least one global image in the control arrangement (6). According to the invention, the respectively detected individual image (7) is evaluated either partially or totally in relation to the contrast thereof, and the obtained contrast values (K) influence the functionality of the entire arrangement.
    • 本发明涉及一种用于光学扫描样品(1)的方法和装置。 该装置包括调整单元(2,3)和包括光学单元(4)和扫描单元(5)的扫描设备(4,5)。 本发明的装置还包括控制光学单元(4),扫描单元(5)和调节单元(2,3)的控制装置(6)。 样品(1)相对于扫描装置(4,5)移动,或反之亦然,借助于被控制装置(6)撞击的调节单元(2,3)而移位。 结果,通过扫描装置(4,5)获得的各个图像(7)被组装成在控制装置(6)中形成至少一个全局图像。 根据本发明,分别检测到的单独图像(7)相对于其对比度部分地或全部地被评估,并且所获得的对比度值(K)影响整个布置的功能。
