20100220312 | BLOOD EXAMINATION APPARATUS - 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. | 09-02-2010 |
20130063729 | OBSERVATION DEVICE - Provided is an observation device which can obtain a phase image of a moving object rapidly with high sensitivity even when using a photodetector having a slow read-out speed per pixel. The observation device | 03-14-2013 |
20130094027 | OBSERVATION DEVICE - Provided is an observation device which can obtain a phase image of a moving object rapidly with high sensitivity even when using a photodetector having a slow read-out speed per pixel. The observation device | 04-18-2013 |
20140073002 | METHOD FOR DETERMINING DIFFERENTIATION LEVEL OF PLURIPOTENT STEM CELLS - The present invention provides a method for determining differentiation level of pluripotent stem cell, comprising a step of determining a flatness of cultured pluripotent stem cell, wherein the flatness is an indication. | 03-13-2014 |
20140078352 | IMAGING DEVICE - An imaging device includes an illumination unit that irradiates a moving object with light A, an optical system that focuses into an image of the object, a detection unit having a light receiving plane on which the image of the object by this optical system is formed, and an analysis unit.

20140340503 | OBSERVATION DEVICE - An observation device is provided with a light source section, a detection section and an arithmetic operation section. The light source section emits light to a moving object from multiple directions. a detection section is disposed on a predetermined plane such that scattered light having an identical scattering angle enters at an identical position, outputs data temporally changing at a frequency corresponding to an amount of Doppler shift of light that reaches at each position on the predetermined plane. An arithmetic operation section performs a one-dimensional Fourier transform with respect to time variables, for data having a position in the first direction on the predetermined plane, a position in the second direction on the predetermined plane, and a time as variables, and extracts data having an identical incident angle relative to the object from the Fourier-transformed data, on the basis of Doppler Effect. | 11-20-2014 |
