Shy Black Hole

Camera Shy Black Holes

In April astronomers announced what is quite possibly, the most extraordinary piece of scientific news ever. They had at last captured an image of the unobservable, always illusive, black hole – cosmic abyss so deep and dense that not even light can escape it.

Earth's Climate System

Earth’s Climate System

Global-scale observations of the Earth’s climate system (including temperature, precipitation, and other parameters) started in the mid-19th century. Modern observational techniques include both direct measurements at the ground and remote-sensing measurements from satellites. Ancient climates (paleoclimates) have been reconstructed as far back as hundreds of thousands of years by studying ice cores, tree rings, and […]

Automation in Grocery Stores

The advent of online shopping ushered into homes across the globe, a revolution in convenience. No longer do consumers have to travel to a store to browse items and make a purchase. Instead, the store would come to them digitally with a click of a button. In the past two decades, the growth of on-line […]

Security Scanning

Security Scanning Program CLEAR

Two decades ago, going through airport security was a simple process. You simply got into “the” line, put your stuff through the x-ray machine, and walked through the metal detector. Today, the process is much more complex, with as many as four different security lines at some airports, various levels of identity verification and screening offered, […]

License Plate Readers

License Plate Readers

The use of license plate readers is increasing in popularity with police and other law enforcement agencies to find stolen cars and catch up with people with expired licenses or active warrants. And when they’re not piggybacking on police cruisers, plate readers are often affixed to utility poles or freeway overpasses, scanning the passing traffic […]

Surveillance Cameras

Types Of Surveillance Cameras

They are everywhere. Security cameras seem to be on every corner, at entry ways at shopping centers, in parking lots, private homes, and businesses. Government agencies, private businesses, and homeowners know that there are now many types of surveillance cameras from which to choose.

CMOS Image Sensors

CMOS Image Sensors

Virtually all digital and video cameras use CMOS image sensors. In the past two decades, numerous advances have been made in this type of imaging technology. Now, CMOS image sensors are beginning to be made with superior quality that will provide a large range of new products for military and aerospace users.

Traffic Cameras

Traffic Cameras

Part of the mystique of driving has often been the possibility of someday getting into a fast car, pointing it in a random direction, and just driving for the sure pleasure of driving.  However, the onward march of technology that has made its way into every area of modern life has also found its way […]

Terahertz Radiation

3D Printing And Terahertz Radiation

Terahertz radiation is used in a wide variety of applications including airport security checks and material analysis in a lab.  The wavelength of this radiation is significantly larger than the wavelength of visible light, as it is in the millimeter range.  It also requires specialized techniques to manipulate the beams and get them into the […]

Ultraviolet Lenses

Ultraviolet Lenses

Ultraviolet lenses are used in many focusing, collimation, or laser applications that operate within the ultraviolet spectrum. They are optical lenses that consist of a single, or multiple elements that have been designed for optimal performance when used in ultraviolet light.
