The Top 5 Technologies From DSS 2014
With more than 450 companies at this year’s event and only three days to explore, it was an almost overwhelming task to try and take in all of the technology on display. Regardless, I did my best, and here is my list of the top five most exciting technologies I caught at the show.
Simplifying The Development Of Handheld NIR Spectroscopy Devices
Portable NIR spectrometers enable innovative and more efficient ways of handling countless applications. I recently spoke with Mariquita Gordon, business manager of DLP embedded products at Texas Instruments, to discuss the company’s new NIR technologies and talk about the emerging market for portable NIR spectrometers.
Photonics And The Future Of Medicine
Photonics West serves as the perennial indicator of market trends for the photonics and optics industries. At this year’s event, held last month in San Francisco, one of the pervasive themes I observed in both the technical conference and the exhibition was the increasing role photonics and optics are playing in the development of advanced biomedical technologies. That trend is poised to continue well into the future.

Lenses And Prisms In Medical Devices For Imaging And Illumination
On the last day of the MD&M East exhibition, Chuck Gerlowski with Precision Optics Corporation spent some time with Medical Device Online to school us on their micro lenses, micro prisms, and more. These components can be used to design CMOS sensors for imaging systems and illumination systems in medical devices.
Thoughts On The New Sensing Focus At DSS In 2014
We asked a few different photonics technology companies about what they thought in regards to the more prominent focus on sensing technology at DSS 2014, and here’s what they had to say.
Better Images Through Precision Motion Control
Jim Gareau with PI spent some time on the last morning of the DSS 2014 exhibition with us to tell us about their precision motion control solutions and how and why they’re able to provide their customers with better images through hexapods, precision motor stages, and Piezo motion devices.
Buzz At Umicore Booth Over New Catalog Lenses
John Franks of Umicore tells about the lenses the company provides for applications involving automotive night vision, defense, security and surveillance, thermography, and personal thermal vision. He also shares some exciting news about new catalog lenses that are currently available.

Heat-Seeking Missile Tech Used For Malaria Diagnosis
Researchers at Monash University and the University of Melbourne have devised a way to use hardware from heat-seeking missiles to produce a test for early and reliable malaria diagnosis. In the project, researchers used a special infrared sensor called a focal plane array (FPA), which was originally created for use in Javelin anti-tank missiles, to seek out the presence of malaria in a blood sample. When the FPA was used in conjunction with an infrared imaging microscope to test a blood smear, it successfully detected the infrared signature from fatty acids in the malaria parasites, enabling researchers to consistently identify malaria-infested blood at early stages of infection.
'Comb On A Chip' Powers New NIST/Caltech Atomic Clock Design
Researchers from the National Institute of Standards and Technology (NIST) and California Institute of Technology (Caltech) have demonstrated a new design for an atomic clock that is based on a chip-scale frequency comb, or a microcomb.
Enhanced NIST Instrument Enables High-Speed Chemical Imaging Of Tissues
A research team from the National Institute of Standards and Technology (NIST), working with the Cleveland Clinic, has demonstrated a dramatically improved technique for analyzing biological cells and tissues based on characteristic molecular vibration "signatures."
The Optical Society Launches Optica, New Open-Access Journal For Highest-Impact Research In The Science Of Light
The Optical Society (OSA) recently published the first issue of Optica, its new open-access, online-only journal dedicated to rapidly disseminating the highest-impact peer-reviewed research across the entire spectrum of optics and photonics.
Can Retinal Imaging Predict Early-Stage Alzheimer’s?
A group of researchers may have discovered a way to use a noninvasive retinal imaging device to reliably predict Alzheimer’s disease years before its actual onset.
Passive Electro-Optical Counter-Countermeasures (EOCCM)
As laser countermeasures proliferate around the world, infantry, aircrews, and electro-optic sensors are at risk of being engaged with little to no warning. A laser countermeasure can adversely affect targeting and navigation functions by jamming or 'spoofing' the sensor through laser illumination or by damaging the sensor through more intense laser illumination. The laser can also be used to detect and track an otherwise covert electro-optic target by sensing retro-reflections off the target’s optics. This article provides a background on traditional protection technologies and explains how electro-optic counter-countermeasures (EOCCMs) can help mitigate the damage that can be inflicted on optical and electro-optical sights.
Short Wave Infrared (SWIR) Imaging For Hyperspectral And Surveillance Systems
Imaging in the short wave infrared (SWIR) wavelength band (0.9um to 2.5um) has generated much attention in recent years with new applications and mission development. Advancements in SWIR sensor and infrared focal plane array (IRFPA) technologies have been the primary drivers to growing interest in areas such as conventional surveillance imaging and other hyperspectral imaging applications. This article touches on two key applications for SWIR detection.
Ensquared and Encircled Energy Testing Attains ‘Automated’ Status
The ensquared and encircled energy (EE) test method is a quantification of the fraction of optical energy present in the aperture of an optics system. This white paper outlines how this method can provide greater accuracy, application flexibility, and even lower overall costs when compared to interferometry and MTF test instruments.
The Fundamentals Of AOTF-Based Spectral Imaging And Polarimetry
Many hyperspectral imaging (HSi) systems use a diffraction grating to split up a line of an image into strips with different wavelengths and so build up a 3D image cube. While this push-broom process works well for capturing hyperspectral images where there is a built-in, one-dimensional relative movement between the camera and the object, there are many situations where band sequential imagers are more effective. This article explores the basics of acousto-optic tunable filter (AOTF) and polarimetric technology and discusses the advantages of using those approaches for hyperspectral imaging. By Alexandre Y. Fong and Jon Ward, Gooch & Housego
