    • The tomographic image capturing device of the present invention comprises a display means (18) configured to: split light from a light source (11) into measurement light and reference light and cause the measurement light and the reference light to be incident to an object (E) and a reference object (49), respectively; capture tomographic images of the object (E) on the basis of interference light generated by superposition of the measurement light reflected from the object (E) and the reference light reflected from the reference object (49); and display tomographic pictures of the object generated on the basis of the captured tomographic images. The tomographic image capturing device has a first image capturing mode and a second image capturing mode. The first image capturing mode is a mode in which the measurement light is two-dimensionally scanned by raster scan to be incident to the object (E) and the tomographic images of the object (E) are captured. The second image capturing mode is a mode in which the measurement light is two-dimensionally scanned by raster scan to be incident to the object (E) and the tomographic images of the object (E) are captured. The raster scan in the second image capturing mode is thinned from the raster scan in the first image capturing mode. The display means (18) is configured to be switchable between a first display mode and a second display mode. The first display mode is a mode in which a plurality of tomographic pictures including a region of interest of the object (E) is selected from among the tomographic pictures generated on the basis of the tomographic images captured in the second image capturing mode and only the selected plurality of tomographic pictures is displayed. The second display mode is a mode in which all of the tomographic pictures generated on the basis of the tomographic images captured in the second image capturing mode are in turn displayed. The capturing of the tomographic images in the first image capturing mode is performed after separately performing a first adjustment operation and a second adjustment operation for adjustment of an image capturing condition necessary for capturing the tomographic images in the first image capturing mode. The first adjustment operation is based on the tomographic pictures displayed in the first display mode. The second adjustment operation is based on the tomographic pictures displayed in the second display mode.
    • 本发明的断层图像拍摄装置包括:显示装置(18),其被配置为:将来自光源(11)的光分成测量光和参考光,并使测量光和参考光入射到物体( E)和参考对象(49); 基于由从物体(E)反射的测量光与从参考物体(49)反射的参考光的叠加产生的干涉光来捕获物体(E)的断层图像; 并且显示基于捕获的断层图像生成的对象的断层摄影图片。 断层图像捕获装置具有第一图像捕获模式和第二图像捕获模式。 第一图像拍摄模式是通过光栅扫描二维扫描测量光以入射到对象(E)并且拍摄对象(E)的断层图像的模式。 第二图像拍摄模式是通过光栅扫描二维扫描测量光以入射到对象(E)并且拍摄对象(E)的断层图像的模式。 在第一图像捕获模式下,第二图像捕获模式下的光栅扫描从光栅扫描中变细。 显示装置(18)被配置为可在第一显示模式和第二显示模式之间切换。 第一显示模式是这样的模式,其中从在第二图像拍摄模式下拍摄的断层图像生成的断层图像中选择包括对象(E)的感兴趣区域的多个断层图像, 显示选择的多个断层图像。 第二显示模式是其中依次显示基于以第二图像拍摄模式拍摄的断层图像而生成的全部断层图像的模式。 在第一图像拍摄模式中拍摄断层图像是在分别执行用于调整在第一图像拍摄模式下拍摄断层图像所需的图像拍摄条件的第一调整操作和第二调整操作之后执行的。 第一调整操作基于以第一显示模式显示的断层摄影图像。 第二调整操作基于以第二显示模式显示的断层摄影图像。
