Photonics Medical Application Notes

1. Application Note: BrightLock® Ultra-G® Optimized Green Laser Performance 2/10/2011
   The BrightLock® Ultra-G® is a breakthrough laser platform based on proprietary BrightLock® semiconductor chip technology.
2. Technical Note: High-Precision Micromachining 9/16/2008
   Laser micromachining is a large and rapidly-growing application area for pulsed lasers. In fact, the general application area of materials processing forms the largest single application market for all lasers sold. Microelectronics in particular is one of the largest industry sectors that uses laser micromachining for a variety of applications including mask repair, chip repair, linkblowing, wafer processing, via-hole drilling and others. Pulsed lasers that are widely used include excimer lasers and Qswitched solid-state lasers such as Nd:YAG and Vanadate systems. By IMRA America, Inc.
3. NDT In Composite Materials With Flash, Transient, And Lockin Thermography 2/16/2012

   Composites are now used in everything from aircraft to prosthetics. By Markus Tarin and Ralph Rotolante

4. Lenses For Diagnostics 10/13/2023

   Medical diagnostics rely heavily on imaging technologies that allow physicians to examine and assess a patient's body structures and functions in great detail.

5. 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.

6. 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.
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. Using Raman Spectroscopy To Detect Malignant Changes In Tissues 5/25/2012

   Accurate, rapid, and non-invasive detection and diagnosis of malignant disease in tissues is an important goal of biomedical research. Optical methods, such as diffuse reflectance, fluorescence spectroscopy, and Raman spectroscopy, have all been investigated as ways to attain this goal. Diffuse reflectance utilizes the absorption and scattering properties of tissues, particularly from cell nuclei and stroma.

10. 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.
