    • A method and an arrangement for detecting the position of the plane XY of an object, which plane XY is to be scanned, and for its positioning in the focal plane X′Y′ of a laser scanner, preferably for a laser scanning microscope. According to the disclosure, it is provided in a method of the type described above that, after a rough orientation of the object carried out by placing on an object holder, a laser beam is directed successively in time to at least three different points P1, P2 . . . Pn located in the scan plane XY of the object and, in doing so, each of the reflections proceeding from the points P1, P2 . . . Pn is imaged on a position-sensitive detector, an actual position value is determined at the detector for each reflection and is compared with a stored reference position value, adjustment commands for changing the inclination of the object holder are obtained from the deviations of the actual position values from the reference position values, and the inclination of the object holder is changed on the basis of these adjustment commands until points P1, P2 . . . Pn are located in the focal plane X′Y′ of the laser scanner.
    • 一种用于检测物体的平面XY的位置的方法和装置,该平面XY将被扫描平面XY,并且用于其定位在激光扫描仪的焦平面X'Y'中,优选地用于激光扫描显微镜。 根据本发明,提供了一种上述类型的方法,在通过放置在物体保持器上进行物体的粗略取向之后,将激光束在时间上连续地指向至少三个不同点P1, P2。 。 。 Pn位于物体的扫描平面XY中,并且在这样做时,每个反射从点P1,P2进行。 。 。 Pn在位置敏感检测器上成像,在检测器处为每次反射确定实际位置值,并与存储的参考位置值进行比较,从实际的偏差获得用于改变物体保持器的倾斜度的调节命令 基准位置值的位置值,并且基于这些调整指令改变对象保持器的倾斜直到点P1,P2。 。 。 Pn位于激光扫描器的焦平面X'Y'中。
