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

2. Application Note: Design For Manufacturability (DFM) In The Life Sciences 3/19/2010
   The inherently interdisciplinary nature of developing instrumentation for the life sciences requires a high level of collaboration between scientists and engineers across the fields of analytical or clinical chemistry, optics, mechanics, material science and microbiology. By Edward Freniere, Ph. D., Richard Hassler, Linda Smith from Lambda Research Corporation; Eric Heinz from Heinz Optical Engineering Company;
3. 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.
4. Application Note: High-Speed Spectroscopy 9/15/2008
   Optical spectroscopy is an almost universal technique for monitoring substances or processes. There are many varieties of spectroscopic techniques for various applications. Some of these applications (combustion research, for example) require very quick measurement times, especially if the process of interest is very fast. By IMRA America, Inc.

6. 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.

7. Advantages of Point Source Emitters: Application Note 4/30/2012

   A Point Source Emitter is similar to a standard LED, however, its well defined circular area (usually 25μm-200μm in diameter) makes it ideal in applications involving encoders, machine vision, medical fiber, and any other application where a precise beam of light is needed. This application note provides background information on Point Source Emitters, and highlights their advantages over standard LEDs.

8. 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.

9. 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.
10. 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.
