    • PROBLEM TO BE SOLVED: To solve the problem that it is difficult for an operator to understand positional relations among tomographic images due to difference in depth of photographing among the tomographic images when the tomographic images are displayed side by side, because an OCT device for simultaneously photographing with a plurality of beams has adjustment mechanisms for reference optical path lengths per beam and therefore depths of photographed tomographic images are different among the beams.SOLUTION: When tomographic images obtained by the plurality of beams are displayed, heights of respective tomographic images are equalized by display position adjustment based on adjustment values of reference optical path lengths per beam to present the tomographic images in such a form that positional relations among the tomographic images are intelligible to the operator.
    • 要解决的问题:为了解决当层析图像并排显示时,由于在断层图像之间的拍摄深度不同导致的断层图像之间的位置关系难以操作的问题,因为OCT 用于与多个光束同时拍摄的装置具有用于每个光束的参考光程长度的调节机构,因此拍摄的断层图像的深度在光束之间是不同的。 解决方案:当显示通过多个光束获得的断层图像时,各个断层图像的高度通过基于每个光束的参考光程长度的调整值的显示位置调整来均衡,以呈现这样的形式的断层图像 断层图像之间的关系对于操作者是可理解的。 版权所有(C)2012,JPO&INPIT
