The SPIE Defense Security & Sensing Show  in Baltimore, which began on Monday and ends today, provided attendees with an exhibit hall full of new products and technologies. If you weren’t at the show, here’s some of what you missed:

LaserMotive  (Kent, WA) had the first public flight of an aircraft system powered by laser over fiber. The company demonstrated InvisiTower powering a small quadrocopter. InvisiTower is a new, portable system that can power any multi-rotor helicopter indefinitely using laser power sent via fiber optic cable, enabling aircraft to stay in the air as long as power is available on the ground. The system is small enough to fit in the back of an SUV, and does not require a pilot to fly — just someone to monitor the video coming from it.

Virtusphere  (Binghamton, NY) demonstrated the Virtusphere, a simulation platform for training military and law enforcement users preparing for dangerous environments. Virtusphere consists of a 10-foot hollow sphere, which is placed on a special platform that allows the sphere to rotate freely in any direction according to the user’s steps. The user walks, runs, jumps, or crawls inside the sphere, viewing the virtual environment through a head-mounted display. The sensors collect and send data to the computer in real time, and the user’s movement is replicated within the virtual environment.

The MUXed North Finder/Tracker from EMCORE  (Albuquerque, NM) is designed for man-portable target locator and tripod target locator systems. It’s accurate from 1 to 4 milliradians, weighs less than a pound, has electrical power requirements of less than 5W, and is insensitive to base motion.

IO Industries  (London, Canada) introduced the Flare CoaXPress 12-megapixel camera with frame rates of over 120 fps at the native 4k x 3k resolution. It can be interfaced directly to frame grabbers and recorders.

The MicroraptorHD from Airborne Innovations  (Lakewood, CO) is a digital video link that combines a dual camera interface, bidirectional digital video, and command and control link. It’s designed for high-definition video transmission from the smallest micro air vehicles.
