    2. Integrated optical coherence analysis system

      Integrated optical coherence analysis system
      Optical coherence tomography (OCT) probe and system designs are disclosed that minimize the effects of mechanical movement and strain to the probe to the OCT analysis. It also concerns optical designs that are robust against noise from the OCT laser source. Also integrated OCT system-probes are included that yield compact and robust electro-opto-mechanical systems along with polarization sensitive OCT systems.

    8. Coherence properties of short cavity swept lasers

      Coherence properties of short cavity swept lasers
      It has been shown theoretically and experimentally that short cavity swept lasers are passively mode locked. We develop a mathematical model of these lasers and the light field solutions are used to predict the coherence length and coherence revival behavior. The calculations compare favorably with data from a 9901100 nm laser swept at 100 kHz suitable for optical coherence tomography applications.

    9. Regenerative mode locked laser swept source for OCT medical imaging

      Regenerative mode locked laser swept source for OCT medical imaging
      An optical coherence analysis system uses a laser swept source that is constrained to operate in a mode locked condition using regenerative mode-locking. This is accomplished by synchronously changing the laser cavity's net gain and/or phase based on time varying intensity of the swept optical signal generated by the laser. This produces a stable pulsation behavior, which is associated with smooth tuning (low optical frequency reference clock jitter ...

    10. Beyond Better Clinical Care: Optical Coherence Tomography's Economic Impact

      Beyond Better Clinical Care: Optical Coherence Tomography's Economic Impact
      The optical coherence tomography (OCT) industry has grown dramatically in its first 25 years, and while the positive effects on patient clinical care are the most important measure of OCT's success, its contributions to the economy in jobs, tax receipts, and healthcare savings are also noteworthy. The field of optical coherence tomography (OCT) has grown dramatically since its discovery in the early 1990s. The commercialization and growth of OCT ...

    11. Optical teardown of a Kindle Paperwhite display by OCT.

      Optical teardown of a Kindle Paperwhite display by OCT.
      An optical teardown, or reverse engineering, of an Amazon Kindle Paperwhite electrophoretic display was performed by Optical Coherence Tomography at 1060 nm. The display incorporates an optical diffuser, lightguide and scattering layers for white light illumination, capacitive touch sensing, and an electrophoretic display. All these layers can be imaged by OCT as well as the thin film transistor array on the back side for driving the pixels. Phase sensitive OCT ...

    12. SNR of swept SLEDs and swept lasers for OCT

      SNR of swept SLEDs and swept lasers for OCT
      A back-to-back comparison of a tunable narrow-band-filtered SLED (TSLED) and a swept laser are made for OCT applications. The two sources are similar in terms of sweep speed, tuning range and coherence length. A fundamental issue with a TSLED is that the RIN is proportional to 1/linewidth, meaning that the longer the coherence length, the higher the RIN and clock jitter. We show that the TSLED has an SNR ...

    13. Swept frequency laser for FD-OCT with intracavity element and method of operation

      Swept frequency laser for FD-OCT with intracavity element and method of operation
      A frequency swept laser source that generates an optical signal that is tuned over a spectral scan band at single discrete wavelengths associated with longitudinal modes of the swept laser source. Laser hopping over discrete single cavity modes allows long laser coherence length even under dynamic very high speed tuning conditions. A ramp drive to the laser is used to linearize laser frequency tuning. A beam splitter is used to ...

    1. The Mass. court's decision is only one ruling of a much broader case involving 30 trade secret claims against Volcano and subsidiary Axsun Technologies Inc.... today's ruling does not call into question the significant jury verdict from February 2010... the decision does not change the Superior Court of Massachusetts' verdict against Axsun Technologies, ruling that the company must ban the sale of its lasers to Volcano for all fields of use, not just the field of human coronary artery imaging.
