Patent number: 9804376Abstract: An instrument and method for scanning all or part of a large specimen mounted on a specimen holder takes a plurality of measurements of each pixel in the whole or part of the specimen being scanned at a plurality of exposure values. A computer controls the movement of the specimen holder during scanning and again of the detector to produce a digitized image of all or part of the specimen with larger dynamic range than the dynamic range of the detection system. In a further embodiment, the instrument can scan two successive, identical strips at a different exposure values and combine the images from the two scans into one digitized image having a larger dynamic range than the dynamic range of the detection system.Type: GrantFiled: March 4, 2013Date of Patent: October 31, 2017Assignee: Huron Technologies International Inc.Inventors: Arthur Edward Dixon, Savvas Damaskinos

Patent number: 9632301Abstract: An instrument and method for scanning a large microscope specimen uses a light source and at least one lens to focus light from the specimen onto a detector array. The specimen holder is located on a scanning stage and the detector array is dynamically tilted about a scan direction during the scan to maintain focus across the width of the scan strip as the scan proceeds. A degree of tilt varies during the scan as is required to maintain lateral focus relative to the detector array.Type: GrantFiled: September 21, 2012Date of Patent: April 25, 2017Assignee: Huron Technologies International Inc.Inventors: Savvas Damaskinos, Arthur Edward Dixon

Patent number: 7218446Abstract: A new high resolution confocal and non-confocal scanning laser macroscope is disclosed which achieves fine focus and control of focus position by moving a lens in the intermediate optics. This arrangement is particularly useful for imaging specimens where it is difficult to focus by changing the distance between the scan lens and the specimen, for example for in-vivo imaging, photodynamic therapy, and image-guided surgery. It is also important to keep the lens-to-specimen distance constant when a liquid-immersion scan lens is used, in order to maintain a constant thickness of liquid between the lens and the specimen. In addition to being useful for confocal slicing, motion of the intermediate lens under computer control also enables dynamic focus and the ability to move the focal spot along a general path inside the specimen. Several applications of the imaging system are described.Type: GrantFiled: August 27, 2003Date of Patent: May 15, 2007Assignee: Biomedical Photometrics Inc.Inventors: Arthur E.

Publication number: 20040263959Abstract: A new high resolution confocal and non-confocal scanning laser macroscope is disclosed which images macroscopic specimens in reflected light, transmitted light, fluorescence, photoluminescence and multi-photon fluorescence. The optical arrangement of a scanning laser macroscope has been altered to include a liquid-immersion laser scan lens, providing higher numerical aperture and higher resolution; and higher intensity at the focal spot, which makes the macroscope particularly well suited for multiphoton imaging. Several applications of the imaging system are described. A liquid-immersion laser scan lens with spring-loaded bottom element and method for containing the immersion liquid are also disclosed.Type: ApplicationFiled: June 30, 2003Publication date: December 30, 2004Inventors: Arthur E.

Patent number: 6243189Abstract: The present invention provides an inexpensive, simple, compact, optical relay for use primarily with scanning beam imaging systems. More specifically, it can be used as an optical interconnect between scanning mirrors and between a scanning mirror and imaging optics such as a microscope objective. The optical relay, also known as an optical telescope or coupler, consists of two eyepieces forming an afocal assembly. A beam pivoting about a stationary point in the first focal plane of the first eyepiece will be relayed through the optical system such that it pivots about a stationary point at the second focal plane of the second eyepiece. In the preferred embodiment a collimated beam pivots about the first focal point of the first eyepiece as it enters the optical relay, and exits the optical relay with the same beam diameter and scan angle (opposite sign) pivoting about the second focal point of the second eyepiece.Type: GrantFiled: April 20, 1999Date of Patent: June 5, 2001Inventors: Alfonso Carlos Ribes, Arthur Edward Dixon, Savvas Damaskinos

Patent number: 6072624Abstract: A non-confocal scanning beam optical imaging or mapping system for macroscopic samples is disclosed, in which an expanded laser beam passes through a scan system and a telecentric laser scan lens focuses the beam to a moving spot in the sample. Light reflected (or emitted) from the illuminated spot is collected by the laser scan lens, descanned by the scan system, and detected by a detector. Transmitted-light and other non-confocal versions are also disclosed. This new scanning beam laser imaging system performs a rapid scan of a large sample. Applications include fluorescent imaging of large biomedical specimens, including fluorescent gels, photoluminescence mapping of semiconductor samples, etc.Type: GrantFiled: May 28, 1998Date of Patent: June 6, 2000Assignee: Biomedical Photometrics Inc.Inventors: Arthur E.
