Patent number: 12146792Abstract: A full-range imaging method doubles imaging range of conventional techniques by removing mirror images of an imaged object that limit conventional images to a “half-range” and that are caused in part by the loss of phase information in a detected signal. Phase information of the detected signal is reconstructed with an averaging technique based on a modulated phase induced in the detected signal during scanning.Type: GrantFiled: December 15, 2023Date of Patent: November 19, 2024Assignee: TOPCON CORPORATIONInventors: Xiang Wei, Tony Ko

Patent number: 8405834Abstract: In one aspect, the invention relates to a method of acquiring optical coherence tomographic data from a sample. The method includes the steps of scanning a first location on the sample to obtain a first set of optical coherence tomographic data, scanning a second location on the sample to obtain a second set of optical coherence tomographic data, and defining a fiducial position relative to a location on the sample using one of the two sets of optical coherence tomographic data. In one embodiment, the first set of optical coherence tomographic data is survey data. However, in another embodiment the first set of optical coherence tomographic data is sample measurement data.Type: GrantFiled: December 28, 2010Date of Patent: March 26, 2013Assignee: Massachusetts Institute of TechnologyInventors: Vivek Srinivasan, James Fujimoto, Tony Ko, Maciej Wojtkowski, Robert Huber

Publication number: 20090054791Abstract: Micro-optical imaging is facilitated. According to an example embodiment, a micro-optical probe arrangement includes a GRIN-type lens probe to direct light to and from a specimen. Compensation optics tailored to the probe and aberrations introduced by the lens are located in a light path through the lens, and compensate for the introduced aberrations. A light detector detects light from the specimen, as facilitated by the compensation optics, and generates data characterizing an image of the specimen.Type: ApplicationFiled: July 17, 2008Publication date: February 26, 2009Inventors: Benjamin A. Flusberg, Mark Jacob Schnitzer, Tony Ko
