BLOOD EXAMINATION APPARATUS |
摘要 |
This blood examination apparatus examines cancer cells mixed in an examination object which is flowing blood, and includes: a flow cell through which the examination object is made to flow; an imaging optical system which light output from the examination object in an examination region in the flow cell enters, the imaging optical system forming an image of the light on a first image plane; a first Fourier transformation optical system which optically two-dimensionally Fourier-transforms the image formed on the first image plane by the imaging optical system to form the Fourier-transformed image on a second image plane; a spatial light filter which selectively allows a portion in a certain range around an optical axis of the first Fourier transformation optical system of the image formed on the second image plane by the first Fourier transformation optical system to pass through; and a second Fourier transformation optical system which optically two-dimensionally Fourier-transforms the portion which has passed through the spatial light filter of the image formed on the second image plane by the first Fourier transformation optical system to form the Fourier-transformed image on a third image plane. |
