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. […]
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. […]
More and more robots and artificial intelligence is being seen throughout the world of technology. Alongside smartphones; fitness accessories and robotic appliances are showing up. Personal, practical and well-designed, these products bundle both robotic hardware and the ease of connected services into consumer-friendly packages for [...]
An optical beam smoke detector is a device that uses a projected beam of light to detect smoke across large areas, typically as an indicator of fire. They are used to detect fires in buildings where standard point smoke detectors would either be uneconomical or restricted for use by [...]
Law enforcement agencies around the globe are beginning to rely more heavily on technology to assist in their roles to keep the peace. The use of CCTV cameras, and more recently, police robots, are aiding in many areas of law enforcement. Over the past 10 [...]
Patrolling high-crime areas in major cities is costly and dangerous. Therefore, it is easy to understand why the use of unmanned drones can help law enforcement fight crime. This method is a topic of discussion in law enforcement departments nationwide. Police departments can now deploy drones to improve their [...]
During this time of vigilance against terrorist activity, in situ detection and testing of seawater for trace levels of explosives is a high priority of the Navy and the DoD, both for protection of U.S. personnel and assets and for environmental monitoring of Navy-patrolled littoral waters. NRL has immersed [...]
Vision-based face detection and recognition is one of the most rapidly growing research areas in computer vision and robotics and is widely used in several human related applications. However, vision-based face detection and recognition has been shown to be effective only under normal illumination conditions. In developing an algorithm [...]
Manufacturers understand they can save money on the lens manufacture process if they can utilize commercial off the shelf (COTS) products. In many areas of military design and government agencies, this COTS model is being adopted because it is a cost saving measure. The key factor to making this [...]
It’s not the size that matters in lenses that were created by engineers from the University of Wisconsin-Madison. The first-ever flexible Fresnel zone plate microlenses offer a wide field of view. The development of these lenses has the potential to allow items from security cameras to surgical scopes to [...]
