Airborne Thermal HSI of Gases using Mapping and Targeting Acquisition Modes

Characterization of freely dispersing gas clouds is a challenging task. The large area covered and uneven distribution of these fast moving entities makes conventional ground based techniques inappropriate in some cases. This application note presents how the targeting and acquisition mode, a unique feature of the Telops Hyper-Cam airborne platform, provides valuable time-dependent information on gas cloud dispersion such as the origin of the gas leak, the gas cloud direction and its velocity.

FAST Thermal Imaging: The New Way to Look at Ballistic Impacts

For numerous years, soldier protection dedicated research groups have been using high-speed visible imaging systems in order to evaluate the level of protection offered by various ballistic materials. The main objective of these studies consists in evaluating the amount of energy absorbed by a given material, and how efficient this material is at spreading the absorbed energy to a large area. Obviously, the outputs lead to the commercialization of better and more efficient soldier protective gear.

FAST Thermal Imaging - Muzzle Flash Analysis

Significant technical challenges need to be overcome when it comes to detection, location, and identification of small caliber hostile gunfire.  The key characteristic for the detection of a small caliber gunfire, which also leads to the most obvious technical challenge, is its short, few milliseconds long, muzzle flash.  Other technical challenges include the detection of the fast moving target and the detection of a high energy event, in real-time while covering a large area (Field of View or FOV).

Real-time Characterization of Smoke Candles Using Infrared Hyperspectral Imaging

The development of efficient countermeasure devices like flares and smoke candles requires detailed characterization in order to suit their proper application. However, the gas clouds produced by these devices may turn out to be difficult to characterize. Infrared hyperspectral remote sensing now brings crucial information to this task which could not be obtained before. The Telops Hyper-Cam, a standoff infrared hyperspectral sensor, was used to characterize smoke candles developed by the Military University of Technology in Poland.

Airborne Detection of Chemical Powders Using Infrared Hyperspectral Imaging

Airborne surveillance is routinely used in applications related to border protection, homeland security, command and control or even maritime surveillance. High Resolution infrared imaging provides to airborne surveillance activities valuable detection capabilities based on target shapes, temperatures and chemical nature. The spectral dimension provided by infrared hyperspectral imaging can add selectivity and efficiency to this task leading to additional tools for the detection and identification of ground targets, based on their unique spectral signature. Integrated into a fully automated gyrostabilized gimbal mounted in front of an helicopter, the Telops Hyper-Cam, an infrared hyperspectral imager, has been used to perform an airborne detection of a benign chemical powder spill (ammonium sulfate).
