Infrared Camera Description and Historical Information
 
This Infrared Camera Range Calculator enables the user to easily estimate the maximum range from which an object can be detected when using various infrared camera platforms. It is important to note that these estimates assume that range performance is based solely on image quality yielding a method of estimation that's simple to implement. The estimates are based solely on the object size, distance, camera objective lens and camera detector parameters. Object temperature, emissivity, atmospheric conditions, reflectivity and other factors are not considered. In this regard, the object size and focal length of the objective lens are variables to be entered by the user. The spreadsheet also provides information as to the angular and spatial field-of-view of different camera systems at a specified range.
 
The calculations used here are based on the "Johnson Criteria" which were developed many years ago by John Johnson, a scientist at the US Army Night Vision Lab (Night Vision & Electronic Sensors Directorate). Johnson was working to develop methods of predicting target detection, recognition, and identification. He was working with volunteer observers using image intensifier equipment and quantified the volunteer observer's ability to identify scale model targets under various conditions. His experiments produced the first empirical data on perceptual thresholds. The so-called Johnson Criteria have been the basis for many models that predict the performance of sensor systems under different environmental and operational conditions. According to the Johnson Criteria, the minimum resolution (pixels on target) required to achieve a 50% probability that an observer can discriminate an object at a certain range to the specified level are:
 
  • Detection - an object is present: 2 +1/-0.5 pixels
  • Recognition - the type object can be discerned, a person vs. a car: 8 +1.6/-0.4 pixels
  • Identification - a specific object can be discerned, a woman vs. a man, the specific car: 12.8 +3.2/-2.8 pixels
High Performance Family
of Scientific Cameras

The SSC Series of high-speed infrared cameras are ideally suited for high performance infrared imaging in the mid-wave (3-5µm), broadband (1-5µm), long-wave (7-10 µm) and the very long wave (7-13 µm) spectral ranges. They incorporate high sensitivity HgCdTe infrared detectors and are designed with a sealed, rugged housing enabling a wide range of applications including tracking, cold temperature work, target signature radiometric data collection, high speed imaging and infrared imaging spectroscopy.

High Speed Infrared Cameras Enable Demanding Thermal Imaging Applications

Recent developments in cooled mercury cadmium telluride (MCT or HgCdTe) infrared detector technology have made possible the development of high performance infrared cameras for use in a wide variety of demanding thermal imaging applications. These infrared cameras are now available with spectral sensitivity in a wide range of bands. Camera features now include high frame rate imaging, adjustable exposure time and event triggering enabling the capture of temporal thermal events. These performance capabilities and camera features enable a wide range of thermal imaging applications that were previously not possible.
