Photonics Medical Application Notes

  1. Pre-, Intra-, And Postoperative Use Of Dynamic Infrared Thermography (DIRT) Provides Valuable Information On Skin Perfusion In Perforator Flaps Used In Reconstructive Surgery 2/17/2012

    A study of dynamic infrared thermography (DIRT) in all three phases of perforator flap surgery.

  2. OCT for Non-Destructive Testing 12/18/2012

    Optical Coherence Tomography (OCT) is an imaging method that scans light across a sample/object, and then processes and transforms the reflected light to create a depth profile of up to several mm. Tornado Spectral Systems has developed a nanophotonic spectrometer for use in this application space. To find out more about optical coherence tomography and how Tornado Spectral can help you unlock the potential of OCT for non-destructive testing applications, download the application note.

  3. Coherent Anti-Stokes Raman Scattering Imaging: A Basic Overview With An Emphasis On The Optics Required 5/11/2012

    Coherent anti-­Stokes Raman scattering (CARS) imaging is a nonlinear optical technique that captures intrinsic molecular vibrations to create optical contrast. It offers submicron level spatial resolution and video-­speed imaging rate without the needs for extrinsic labels. In a CARS process, a pump laser, a Stokes laser and a probe laser (usually same as the Pump laser) are involved.

  4. Flexible Fluorescence Technical Tip 1/22/2013

    Fluorescence is one of the most beautiful phenomena in nature, as fascinating to us today as it was for early scientists. It occurs throughout nature: gemstones, minerals, chlorophyll and even crude oil residues fluoresce. And though fluorescence began as a field of scientific study, it has evolved and matured into a technique that now enables entire fields of cutting-edge science and medicine.

  5. Application Note: Detection Of Hydrocarbon Radicals During Plasma Etching 4/16/2010

    Optical emission spectroscopy is used to study and monitor the plasma etching of hydrogenated amorphous carbon (a-C:H) thin films. T.A.R. Hansen and R. Engeln, Eindhoven University of Technology

  6. Optical Coherence Tomography 9/26/2022

    Optical coherence tomography (OCT) is a noninvasive, high-resolution optical imaging technology that creates cross-sectional images from interference signals received from an object under investigation and a local reference.

  7. Photodiode Typical Applications 3/22/2011
    Photodiodes are unique among light detectors in that when illuminated, they generate an output which is proportional to light level. By Excelitas Technologies
  8. Application Note: Nonlinear Microscopy 9/16/2008
    Ultrafast lasers have revolutionized the field of microscopy by enabling new types of nonlinear microscopy techniques. Femtosecond pulse lasers provide the combination of high peak power (1-100 kW) and low average power (10-1000mW) which is ideal for utilizing nonlinear optical processes in scanning laser microscopy (LSM). Here, we describe the two main varieties of nonlinear microscopy: two-photon microscopy, and third-harmonic generation (THG) microscopy. And we show images using these techniques with various types of modelocked fiber lasers. By IMRA America, Inc.
  9. Application Note: Medical X-Ray Imaging System Improves Patient Diagnosis 8/20/2010
    For more than 40 years, Italray srl has been a manufacturer of radiological equipment for traditional and digital medical applications, and of computer-assisted systems dedicated to radiological purposes. In recent years, Italray’s laboratories have developed the X-Frame line of digital imaging systems, which includes the X-Frame CCD series for radiology/fluoroscopy applications. With the help of image acquisition boards and software from DALSA, X-Frame CCD systems provide the high-speed image acquisition, real-time data processing and storage capabilities, and image reliability needed to address the challenges of the applications for which the systems were developed.
