Filters are devices that allow specific stuff to pass through them and reject or block the rest. In the context of optical communication, optical filters are used for pretty much the same thing. Optical filters promote the transmission of different wavelengths while absorbing those that are not required — they [...]
NATO, Russia, and China have been engaged in a new arms race for quite a while. The top prizes now include hypersonics, railguns, and lasers. After years of study and development, not to mention billions of dollars spent, the three technologies are now finally starting to take shape. [...]
Poor air quality is a tell-tale sign of the widespread air pollution that has blanketed our country for several years. With rising concerns about air pollution, federal authorities are now turning to science and technology to develop advanced air quality monitoring systems. […]
Rapid explosive detection is vital to protecting lives as well as significant damage to the property. In the past, there have been a number of methods to identify explosives and prohibit them from being transported across the U.S. borders; for example, imaging and chemical identification. That being said, none of [...]
Tens of thousands of international travelers cross secure U.S. borders on a day to day basis, with just about every one of them carrying some sort of hand baggage. It is the duty of the U.S. Customs and Border Protection (“CBP”) to thoroughly check the traveler’s luggage before they are [...]
Governments all over the world are joining forces to address the issue of climate change. With the increase in global warming driven by human greenhouse gas emissions and the resulting large-scale shifts in weather patterns, space agencies have also entered the fight to heal the Earth’s climate. [...]
The military is, beyond the shadow of a doubt, the most vital asset of any country. A capable military represents a strong nation. As a result, most of the hi-tech innovations are devised while keeping military applications in mind. Unmanned robots are no exception. They, too, are designed to reinforce [...]
It is not every day that businesses deal with the problem of receiving counterfeit currency. Be that as it may, this act of forgery — despite its infrequency — cannot be overlooked. It goes without saying that this deliberate attempt to defraud the receiver is fraudulent, and that makes it [...]
Night vision was first used in the military in the 1930s on German tanks. These devices provided much better vision than the naked eye but the original version was expensive and heavy. […]
New and expanding ideas of how we look at things is growing almost at an exponential pace. Engineers, scientists and designers are always looking for ways to see things we’ve never seen before. One piece of this emerging technology is what’s known as Time-of-Flight (ToF) cameras. The easiest way of [...]
