Patent number: 10598916Abstract: In an image acquisition device, an optical path difference generating member can form an optical path length difference of a second optical image without splitting light in a second optical path. This can suppress the quantity of light required for the second optical path to obtain information of the focal position, whereby a quantity of light can be secured for a first imaging device to capture an image. The image acquisition device synchronizes the movement of a predetermined part of a sample within a field of an objective lens with rolling readout such that each pixel column of a second imaging device is exposed to an optical image of the predetermined part in the sample.Type: GrantFiled: May 8, 2019Date of Patent: March 24, 2020Assignee: HAMAMATSU PHOTONICS K.K.Inventors: Fumio Iwase, Masatoshi Okugawa

Patent number: 10422987Abstract: In an image acquisition device, imaging is performed using an imaging element capable of rolling reading an optical image of a sample irradiated with instantaneous light. Therefore, the image can be captured with a sufficient S/N ratio even when the optical image is weak. Further, the image acquisition device includes a light source control unit that causes the instantaneous light to be emitted from a light source from the start of exposure of a pixel row of which reading last starts to the start of reading of a pixel row of which the reading first starts. That is, in the image acquisition device, the light source control unit causes the sample to be irradiated with the instantaneous light from the light emitting means during a period of time in which all pixel rows of the imaging element are exposed.Type: GrantFiled: January 28, 2014Date of Patent: September 24, 2019Assignee: HAMAMATSU PHOTONICS K.K.Inventor: Fumio Iwase

Patent number: 10348954Abstract: An image acquisition device reciprocates a focal position of an objective lens with respect to a sample in the optical axis direction of the objective lens, while moving a field position of the objective lens with respect to the sample. This makes it possible to acquire contrast information of image data at the field position of the objective lens sequentially as the field position moves with respect to the sample. The image acquisition device acquires the image data by the rolling readout of the image pickup element according to the reciprocation of the focal position of the objective lens.Type: GrantFiled: April 21, 2014Date of Patent: July 9, 2019Assignee: HAMAMATSU PHOTONICS K.K.Inventors: Fumio Iwase, Masatoshi Okugawa

Patent number: 9911028Abstract: In this image acquisition device, a stage driving unit moves a position of a field of view of an objective lens relative to a sample at a predetermined velocity, and a two-dimensional imaging element sequentially captures an optical image of the sample at a predetermined frame rate. Therefore, time required for acquiring partial images over the entire sample is shortened. Further, in this image acquisition device, the moving velocity of the position of the field of view is a velocity set based on a frame rate of the imaging element. Therefore, the movement of the position of the field of view and the imaging of the imaging element are synchronized with each other, and it is possible to capture only necessary partial images.Type: GrantFiled: January 28, 2014Date of Patent: March 6, 2018Assignee: HAMAMATSU PHOTONICS K.K.Inventor: Fumio Iwase
