Photonics Medical Application Notes

1. 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.
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. Measuring The Opacity Of Plastic Tubing With VIS-NIR Transmission Spectroscopy 1/22/2013

   Plastic tubing is available in a variety of opacities ranging from clear to translucent. The transparency of plastic tubing is varied for a number of reasons including providing contrast for visual monitoring of fluid flow, decreasing exposure to ambient light and making the tubing more distinct for machine vision technology. In this application note, VIS-NIR transmission spectroscopy is used to assess the amount of frosting applied to plastic tubing to determine if the tubing meets the required opacity level.

4. Technical Note: Nanoparticle Generation With Femtosecond Pulsed Laser Deposition 9/16/2008
   Deposition technology is used in the semiconductor and flat panel display industries, along with being used for MEMS, nanotechnology, and optics. Pulsed laser deposition (PLD) with ultrashort pulses has been demonstrated using various ultrafast lasers. In this note, generation and deposition of uniform nanoparticles via femtosecond laser ablation will be described. By IMRA America, Inc.

6. The Evaluation Of Increase And Distribution Of Temperature During The Dental Drilling Using A Thermal Imaging Camera 2/17/2012

   This paper discusses the use of infrared technology to study the optimal method for post space preparation of teeth including how long to drill, the type and size of dental drill used, and the type of cooling used.

7. 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.

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.
