The Third Infrared Window
8/4/2016
Long wave infrared (LWIR) and mid-wave infrared (MWIR) sensors and cameras have been used in military settings for detecting human activity through thermal emissions. Using the short wave infrared (SWIR) portion of the spectrum extends unique capabilities that often compliment LWIR and MWIR imaging.

Impressions From BiOS 2013
4/4/2013
The SPIE annual conferences, BiOS and Photonics West, recently ended for 2013 with a record number of more than 2,000 technical papers presented on biophotonics methods, systems, and applications. The diversity of applications of optical coherence tomography (OCT) continues to expand, with papers featuring new 3D and even 4D imaging capability in the eye, arteries, and lungs. Raman spectroscopy and NIR spectroscopy had significant sessions for biomedical applications, as did diffuse optical tomography (DOT). It is an exciting time for biophotonics, with new companies thinking out of the box to innovate healthcare diagnostics and solutions. It reminds me of the excitement of the 1990s during the expansion phase of digital telecom, as students graduated from the research labs and began applying their knowledge to real-world problems.

The Growing Impact Of The NIR Wavelength Band To Biophotonics And In Our Lives
11/28/2011
It is a fascinating time to be involved in optics as biological applications grow in leaps and bounds. The National Institutes of Health (NIH) has expanded its innovative “Bench-to-Bedside” funding initiative, which was developed to help speed the delivery of promising laboratory discoveries into new medical and clinical treatments, and it is driving research in optical methods.
