Patent number: 12201360Abstract: An optical coherence tomography (OCT) system for imaging a retina applies a user specific focus correction to focus a sample arm light beam on the user's retina. An OCT image detector generates an OCT signal. A control unit monitors the OCT signal, controls a reference arm optical path length adjustment mechanism to identify a length of the reference arm optical path for which the OCT signal corresponds to an OCT image of the retina, and varies an operational parameter of the sample arm light beam focus mechanism over a range, while maintaining the length of the reference arm optical path for which the OCT signal corresponds to the OCT image of the retina, to identify a focus correction for the user, based on the OCT signal, for application to the sample arm light beam.Type: GrantFiled: January 9, 2023Date of Patent: January 21, 2025Assignee: Notal Vision, Ltd.Inventors: Amit Pascal, Gidon Goren-Gratzyani

Patent number: 11986241Abstract: Retinal imaging systems and related methods employ a user specific approach for controlling the reference arm length in an optical coherence tomography (OCT) imaging device. A method includes generating a signal indicative of a position of a feature of a user's head relative to an OCT imaging device. A user specific reference arm adjustment length range for the user within a reference arm adjustment length range of the OCT device is determined based on the signal. A reference arm length adjustment module is controlled during an imaging of the retina to vary a reference arm length of the OCT imaging device within the user specific reference arm adjustment length range to identify an imaging reference arm length for which an OCT image detector of the OCT imaging device produces an OCT signal corresponding to the retina of the user.Type: GrantFiled: August 31, 2022Date of Patent: May 21, 2024Assignee: Notal Vision, Ltd.Inventors: Amit Pascal, Omer Rafaeli, Yair Alster, Gidon Goren-Gratzyani

Patent number: 11723536Abstract: Ophthalmic imaging systems and related methods provide pseudo feedback to aid a user in aligning the user's eye with an optical axis of the imaging system. An ophthalmic imaging system includes an ophthalmic imaging device having an optical axis, a display device, an eye camera, and a control unit. The display device displays a fixation target viewable by the user. The eye camera images the eye to generate eye image data. The control unit processes the eye image data to determine a position of the eye relative to the optical axis, processes the position of the eye relative to the optical axis to generate a pseudo position of the eye relative to the optical axis, and causes the display device to display an indication that provides feedback to the user that the eye is located at the pseudo position of the eye relative to the optical axis.Type: GrantFiled: June 28, 2022Date of Patent: August 15, 2023Assignee: Notal Vision, Ltd.Inventors: Amit Pascal, Omer Rafaeli, Yair Alster, Gidon Goren-Gratzyani

Publication number: 20230101855Abstract: Retinal imaging systems and related methods employ a user specific approach for controlling the reference arm length in an optical coherence tomography (OCT) imaging device. A method includes restraining a user's head relative to an OCT imaging device. A reference arm length adjustment module is controlled to vary a reference arm length to search a user specific range of reference arm lengths to identify a reference arm length for which the OCT image detector produces an OCT signal corresponding to the retina of the user. The user specific range of reference arm lengths covers a smaller range of reference arm lengths than a reference arm length adjustment range of the reference arm length adjustment module.Type: ApplicationFiled: August 31, 2022Publication date: March 30, 2023Applicant: Notal Vision Ltd.Inventors: Amit Pascal, Omer Rafaeli, Yair Alster, Gidon Goren-Gratzyani
