Patent number: 6798571Abstract: An illumination system for microscopic digital montage imaging based on a pulsed light illumination source triggered by the position of a specimen with respect to the optical axis of the microscope. The strobe illumination is used to facilitate high-speed tiled (montage) image capture of otherwise static specimens with higher throughput and significantly reduced mechanical precision requirements and cost. The invention allows for perfectly aligned montage tiles at high throughputs using standard microscope optics, having camera frame rate be the limiting factor in microscopic tiled image capture.Type: GrantFiled: January 11, 2001Date of Patent: September 28, 2004Assignee: InterScope Technologies, Inc.Inventors: Arthur W. Wetzel, John R. Gilbertson, II, Jeffrey A. Beckstead, Patricia A. Feineigle, Christopher R. Hauser, Frank A. Palmieri, Jr.

Patent number: 6788454Abstract: A viewing apparatus with a photographing function, includes a viewing optical system by which an image of an object, formed by a positive objective optical system, is viewed though a positive eyepiece optical system, and a photographing optical system which is provided independently from the viewing optical system. The photographing optical system covers substantially the same field of view as that of the viewing optical system. The viewing apparatus satisfies the following condition: 0.1<ft/fo<0.7 (1) wherein ft designates the focal length of the photographing optical system, and fo designates the focal length of the objective optical system of the viewing optical system.Type: GrantFiled: September 27, 2002Date of Patent: September 7, 2004Assignee: PENTAX CorporationInventor: Tetsuya Abe

Publication number: 20040125440Abstract: A scanning laser microscope includes a laser generation unit which generates a laser beam, a light modulation unit which modulates the laser beam, a scanning unit which scans a sample, a light receiving unit which receives a light from the sample, a control unit which controls the light modulation unit for each pixel of a scanning image acquired by the light receiving of the light receiving unit, and a storage unit which stores a plurality of controlled patterns. The number of pixels of the patterns correspond to the number of pixels of the scanned image. A modulation information of the laser beam is set for each pixel. The control unit reads the control patterns stored in the storage unit, controls the light modulation unit based on the modulation information of each pixel, and performs such control that the control patterns are changed at an arbitrary timing.Type: ApplicationFiled: December 15, 2003Publication date: July 1, 2004Applicant: Olympus Optical Co., Ltd.Inventor: Yujin Arai

Publication number: 20040090672Abstract: A terrestrial telescope with a digital camera has a TTL light-measurement system for controlling the exposure. For this the imaging element for taking pictures is used to determine exposure control data in response to the first shutter operation. The exposure control data thus determined is used as a basis for controlling the following sequential picture-taking/recording processing in a speed mode until it is cancelled. The camera is able to take pictures in a continuous sequence in which the interval between pictures is very short.Type: ApplicationFiled: December 19, 2002Publication date: May 13, 2004Inventors: Yoshihide Goto, Takayuki Ishida, Shuichi Tominaga, Yasunari Ooguchi
