    1. Light detection and ranging system with photonic integrated circuit

      Light detection and ranging system with photonic integrated circuit

      Disclosed herein are optical integration technologies, designs, systems and methods directed toward Optical Coherence Tomography (OCT) and other interferometric optical sensor, ranging, and imaging systems wherein such systems, methods and structures employ tunable optical sources, coherent detection and other structures on a single or multichip monolithic integration. In contrast to contemporary, prior-art OCT systems and structures that employ simple, miniature optical bench technology using small optical components positioned on a substrate, systems and methods according to the present disclosure employ one or more photonic integrated circuits (PICs), use swept-source techniques, and employ a widely tunable optical source(s). In another ...

    2. Optical probe using multimode optical waveguide and proximal processing

      Optical probe using multimode optical waveguide and proximal processing

      An optical probe includes an optical source that generates an optical beam that propagates from a proximal end to a distal end of an optical fiber that imparts a transformation of a spatial profile of the optical beam. An optical control device imparts a compensating spatial profile on the optical beam that at least partially compensates for the transformation of the spatial profile of the optical beam imparted by the optical fiber in response to a control signal from a signal processor. A distal optical source generates a calibration light that propagates through the one or more optical waveguides from ...

    4. Russian Academy of Sciences Gets New Leader - Congratulations to Alexander Sergeyev a Former OCT Researcher

      Russian Academy of Sciences Gets New Leader - Congratulations to Alexander Sergeyev a Former OCT Researcher

      Russian President Vladimir Putin approved physicist Alexander Sergeyev as the new leader of the prestegious Russian Academy of Sciences. Dr. Sergeyev (sometimes spelled Sergeev) was involved in pioneering research in the early days of Optical Coherence Tomography. For more information see recent ARTICLE and see some of Dr. Sergeyev's list of OCT related articles HERE.

    5. Cubic meter volume optical coherence tomography

      Cubic meter volume optical coherence tomography

      Optical coherence tomography (OCT) is a powerful three-dimensional (3D) imaging modality with micrometer-scale axial resolution and up to multi-GigaVoxel/s imaging speed. However, the imaging range of high-speed OCT has been limited. Here, we report 3D OCT over cubic meter volumes using a long coherence length, 1310 nm vertical-cavity surface-emitting laser and silicon photonic integrated circuit dual-quadrature receiver technology combined with enhanced signal processing. We achieved 15 μm depth resolution for tomographic imaging at a 100 kHz axial scan rate over a 1.5 m range. We show 3D macroscopic imaging examples of a human mannequin, bicycle, machine shop gauge ...

    6. Volcano Corporation Enters $11M Supply Agreement with Santec for Swept Source Lasers

      Volcano Corporation Enters $11M Supply Agreement with Santec for Swept Source Lasers

      Volcano Corporation recent Form 8K filing indicates that it has entered an $11.3M supply agreement with Santec Corporation to supply tunable lasers for its intravascular swept source optical coherence tomography (SS-OCT) product. The text at the bottom of this article shows a page from Volcano’s recent 8k filing (see Link ). Volcano has been through a long and tortuous path to get a swept source laser for its OCT product since it announced the acquisition of Axsun Technology in December 2008. One of the reasons that Volcano acquired Axsun was Volcano thought that Axsun had swept source laser technology ...
