Secure Optical Quantum Communications
NASA’s Glenn Research Center has developed a method of using entangled-photon pairs to produce highly secure mobile communications that require mere milliwatts of power. Conventional gas Argon-ion laser sources are too large, expensive, and power-intensive to use in portable applications. By contrast,...

Optical Product and Document Security Method
An inexpensive security method for uniquely marking and identifying physical objects such as documents or labels has been developed. This technology uses the mixing of inks in numerous different ratios to print arbitrary marks on a given object. The ink mixture used in a printed mark produces a unique,...
Briefs: Medical
A method was developed for concurrently measuring bending and twisting along an optical fiber using only the properties of light guided within the fiber. The method exploits polarization-dependent...

Development of Sodium Lidar for Spaceborne Missions
The metal layers at mesospheric altitudes are excellent tracers of neutral atmosphere dynamics, and have been used since the 1960s to study the chemistry and dynamics of the mesosphere. Ablation from meteors is believed to be the chief source of metals such as Na, Mg, K, Fe, and Ca in the middle...

New Optics See More with Less
NASA's Marshall Space Flight Center has developed a technology that combines a panoramic refracting optic (PRO) lens with a unique detection system to acquire a true 360-degree field of view. Although current imaging systems can acquire panoramic images, they must use up to five cameras to obtain the full field of...
Briefs: Test & Measurement
Time of flight is an approach that gauges distance by measuring the time it takes light projected into a scene to bounce back to a sensor. In time-of-flight imaging, a short burst of light is fired into...

Dual-Field-of-View Multiband Optics
Multi-spectral-band systems are steadily emerging as a desired feature in a camera system. Each spectral band offers different image characteristics. Shorter-wavelength spectral bands provide the potential for better resolution due to the smaller impact of diffraction on the size of the optics blur. This means...

Researchers at MIT and several other institutions have developed a method for making photonic devices — similar to electronic devices but based on light rather than electricity —...
Briefs: Sensors/Data Acquisition
Spectral images, which contain more color information than is obtainable with a typical camera, reveal characteristics of tissue and other biological samples that can't be seen by the...
Briefs: Medical
Doctors currently rely on external ultrasound probes, combined with pre-operative imaging scans, to visualize soft tissue and organs during minimally invasive procedures, as the miniature surgical...
News: Photonics/Optics
For years many engineers have assumed that you cannot encode more than one holographic image in a single surface — at least without losing resolution. Caltech researchers made the idea a reality.
