Photonic Railway: Will Laser Propulsion Enable Interstellar Travel?
Earlier this month, NASA pumped a second infusion of cash into the research of Dr. Young K. Bae, a physicist with 25 years' experience in advanced propulsion concepts. The $500,000 award will support further development of Bae’s patented Photonic Laser Thruster (PLT) technology, which the inventor believes will one day transport humans to other solar systems. This article explores how PLTs work and how they could enable the development of a photonic railway between solar systems.
Disappearing Skyscraper: The Latest In Invisibility Cloaking
Builders in South Korea will soon begin construction on Tower Inifinity, a 1500-foot-high skyscraper that will periodically vanish from sight. Learn about the optical technology behind its disappearing act, and how it is representative of a growing trend in cloaking technology.
First Tunable Diamond Raman Laser Developed
Researchers have developed the world’s first tunable diamond-based Raman laser, capable of producing a broad range of output wavelengths. The device — also the first-ever continuously operating diamond Raman laser — could lead to more targeted treatments for skin and eye disorders, as well as improvements in pollution monitoring and aeronautical engineering.
Canon’s laser Doppler velocimiters benefit from an optical system that can provide accurate, precise measurement in semiconductor laser velocity, even when those lasers are subjected to temperature changes. The optical system uses the diffraction laser light Doppler method, which means that velocity measurements are not dependent upon the semiconductor laser’s wavelength.

How To Increase Production Rate Without Compromising Product Quality
For most world-leading manufacturers, product defects and low quality are unacceptable. Deployment of infrared vision systems is among the most efficient and promising solutions to quickly identify manufacturing defects on the production line and to immediately sort and reject faulty materials. The real-time inspection of goods using modern high-speed infrared imaging systems is not only limited to finding defects, but it also provides key information pertaining to the output quality from automated assembly and production systems. Because of their great sensitivity (down to few mK), high-speed infrared cameras now allow for real-time detection of defects and trending with unprecedented efficiency.

New Image Analysis Technology Improves 1D Barcode Reading Performance
If contemporary technology has a grand theme, it is that eventually digital will replace analog, and solid state will replace mechanical. Mechanical, analog machines have been around for decades, in some cases centuries. They are mature technologies — the kinks have been worked out, the costs have been squeezed as much as possible, the strengths and weaknesses are well understood. The newer solid-state, digital challengers at ﬁrst offer more promise than performance, but with continued innovation and development they come to dominate the market.

Small Pixels And CCD Versus CMOS Update For Global Security And Industrial Imaging Applications
There is a lot of buzz about the improved camera that will be available in the iPhone 5S released this month. One of the surprising announcements from Apple was the increase in pixel size from 1.4um to 1.5um and the statement “bigger pixels = better picture.” This got us thinking about a topic we previously discussed in detail about why cameras for consumer electronic products are not used for machine vision or global security applications.

Therapeutic Laser Systems Improve Quality Of Life In An Aging Global Population
Our global population is aging at an unprecedented rate. The global population of children under the age of five is expected to fall by 49 million by midcentury, while the number of people over age 60 is expected to grow by 1.2 billion, according to the United Nations. An aging population brings with it increased demands on healthcare systems. Governments have to reduce healthcare costs while maintaining quality of life. Today, illnesses are treated according to symptoms, but, in the future, with the help of lasers it will be possible to detect and cure illnesses before their critical phase and, hence, cut the high costs of hospitalization.
