11.12.19 -- The Impact Of Infrared On The Military Test Range

What To Consider When Selecting An IR Camera For Military Test Range Applications
Thermal cameras can allow many types of infrared measurements on the military test range. Depending on what you want to measure, you can choose the wavelength of the camera, the speed, the type of spectral filters and optics you want to use, and how much to spend. Here are some of the factors you should keep in mind when purchasing an IR camera.
Finding Resolution In A Distant Image
Spatial resolution in any remote sensing device is measured in terms of the instantaneous field of view. It is an important consideration for IR cameras on the military test range that need to focus on far-away objects. Despite common misperceptions, zoom lenses work in IR cameras, but understanding spatial resolution is key.
Measurements At The Speed Of Light
There are many applications on the military test range that can benefit from IR cameras capable of making high-speed measurements. Various factors affect whether a camera is suitable for such an application, including lens speed, pixel pitch, and the waveband it covers. Understanding those factors will help users determine if a camera is suited for the job.
The Challenges Of Infrared Radiance Measurement

Radiance is the amount of light coming off an object in a particular part of the spectrum at a specific temperature. IR cameras are used on the military test range primarily to measure the radiance of various targets. Understanding how radiance measurements work allows users to decide whether a camera is properly calibrated for their application.

Software: A Critical Component Of Any IR Camera

Software provides users of IR cameras with a work environment in which all the camera functions take place. Choosing the right software can greatly expand the capabilities of an IR camera.
