Application Notes

Thermal Infrared Multispectral Imaging of Minerals

For years, scientists have used thermal broadband cameras to perform target characterization in the longwave (LWIR, 8-12 µm) and midwave (MWIR, 3-5 µm) infrared. The analysis of broadband imaging sequences typically provides energy, morphological and/or spatiotemporal information. However, there is very little information about the chemical nature of the investigated targets when using such systems due to the lack of spectral content in the images.

Time-resolved Multispectral Imaging of Gases

For years, scientists have used thermal broadband cameras to perform target characterization in the longwave and midwave infrared. The analysis of broadband imaging sequences typically provides energy, morphological and/or spatiotemporal information. However there is very little information about the chemical nature of the investigated targets when using such systems due to the lack of spectral content in the images. In order to improve this situation, Telops has developed dynamic multispectral imaging systems which allow synchronized acquisition on 8 channels, at a high frame rate, using a motorized filter wheel.

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).
