血液检查装置
摘要：
本发明涉及一种血液检查装置。该血液检查装置是以流动的血液为检查对象物，检查混合存在于该检查对象物的癌细胞的装置，其具备：流动室，流动有检查对象物；成像光学系统，输入位于流动室中的检查区域的检查对象物所输出的光，并在第1像面上形成该光的像；第1傅里叶变换光学系统，对由成像光学系统在第1像面上形成的像进行光学二维傅里叶变换，并在第2像面上形成该像的傅里叶变换后的像；空间光滤波器，使由第1傅里叶变换光学系统在第2像面上形成的像中的、以第1傅里叶变换光学系统的光轴为中心的一定范围的部分选择性地通过；以及第2傅里叶变换光学系统，对由第1傅里叶变换光学系统在第2像面上形成的像中的、通过了空间光滤波器的部分进行光学二维傅里叶变换，并在第3像面上形成该像的傅里叶变换后的像。
摘要（英）：

A blood examination apparatus for examining cancer cells mixed in a flowing blood handled as an examination subject comprises a flow cell through which an examination subject is flowed, an image-forming optical system for receiving light output from an examination subject in an examination region inside the flow cell and forming an image on a first image plane by focusing the light, a first Fourier transform optical system for implementing optical two-dimensional Fourier transform of the image formed on the first image plane and forming the image after the Fourier transform on a second image plane, a spatial optical filter for selectively passing a specific area which is a part of the image formed on the second image plane and the center of which is the optical axis of the first Fourier transform optical system, and a second Fourier transform optical system for implementing optical two-dimensional Fourier transform of the part of the image formed on the second image plane and passed through the spatial optical filter and forming the image after the Fourier transform on a third image plane.
