    2. 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 ...

    3. 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 ...

    4. 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 ...

    5. 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 ...

    6. 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 ...

    7. OCT swept laser with high coherence signal extraction

      OCT swept laser with high coherence signal extraction
      An optical coherence tomography system utilizes an optical swept laser that has improved coherence length in the swept optical signal. This is accomplished using an intra-cavity element that extracts the tunable optical signal at the optimal location within the laser's resonant cavity. Generally this location is between the intracavity tuning element and the cavity's gain element so that light coming from the tuning element is extracted. In general ...

    8. Spectral filtering of k-clock signal in OCT system and method

      Spectral filtering of k-clock signal in OCT system and method
      A system and method for spectral filtering of a k-clock signal in a swept-source Optical Coherence Tomography ("OCT") system to remove artifacts in the k-clock signal. The system synchronizes sampling of the k-clock and interference signals generated from scanning a sample. Using a filtered k-clock signal, the system resamples an interference dataset of the interference signals. The system then performs Fourier transform based processing upon the resampled interference dataset to ...

    9. Multimodal ophthalmic imaging using swept source spectrally encoded scanning laser ophthalmoscopy and optical coherence tomography

      Multimodal ophthalmic imaging using swept source spectrally encoded scanning laser ophthalmoscopy and optical coherence tomography
      Scanning laser ophthalmoscopy (SLO) and optical coherence tomography (OCT) benefit clinical diagnostic imaging in ophthalmology by enabling in vivo noninvasive en face and volumetric visualization of retinal structures, respectively. Spectrally encoding methods enable confocal imaging through fiber optics and reduces system complexity. Previous applications in ophthalmic imaging include spectrally encoded confocal scanning laser ophthalmoscopy (SECSLO) and a combined SECSLO-OCT system for image guidance, tracking, and registration. However, spectrally encoded imaging ...

    10. Multi-speed OCT swept source with optimized k-clock

      Multi-speed OCT swept source with optimized k-clock
      An optical coherence tomography system utilizes an optical swept source that frequency scans at least two different sweep rates. In this way, the system can perform large depth scans of the sample and then the same system can perform shorter depth high precision scans, in one specific example. In order to optimally use the analog to digital converter that samples the interference signal, the system further samples the interference signals ...

      Optical Coherence Tomography Industry Has Provided Well Over 20,000 Person-Years of Direct Employment
      The field of Optical Coherence Tomography (OCT) has grown dramatically since its discovery in the early 1990s. The commercialization and growth of OCT which has occurred over the past 25 years has been highly impactful, scientifically, clinically, and economically. Many factors have helped drive this success starting with the clinical need for new cost-effective high-resolution minimally-invasive imaging solutions for various diagnostic and therapeutic applications. But equally important to this success ...

    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.
