  • Publication number: 20240008736
    Abstract: A multi-modal system that can perform optical coherence tomography (OCT), scanning laser ophthalmoscopy (fluorescence and reflectance), adaptive optics enhancement, and OCT-angiography simultaneously is presented. Such a system minimizes registration errors in multi-modality images, and accelerates biomedical research. Such a system could also permit enhanced high-speed diagnosis. This system would also permit a wide-selection of excitation wavelengths to measure fluorescence intensity from a variety of fluorophores and auto-fluorescing tissues. A novel animal positioning system that can easily align with the imaging beams for optimal image quality and high-speed experiment-setup and imaging of animals is also presented.

  • Patent number: 9816803
    Abstract: Optical Coherence Tomography (OCT) system and apparatus of this instant application is very useful for diagnosis and management of 3ophthalmic diseases such as retinal diseases and glaucoma etc. Instant innovative OCT diagnostic system leverages advancements in cross technological platforms. The Michelson interferometric system presented in this application could be used for the OCT imaging, which includes biological OCT imaging, medical OCT imaging, ophthalmic OCT imaging, corneal OCT imaging, retinal OCT imaging, and the like. A tunable filter is placed in front of the detector to make the interferometer more sensitive and accurate for examining various samples for diagnosis.
