Identification

To define what is meant by “seeing a target”, the so-called Johnson’s criteria can be used.
John Johnson, a Night Vision & Electronic Sensors Directorate scientist, developed criteria that relate to the effective range of infrared cameras. Although developed for the military (hence the use of the term “target” to refer to the object of interest),
the Johnson criteria are widely used in the commercial marketplace to characterize thermal imaging systems.
According to these criteria a distinction needs to be made between degrees of “seeing” a target:
An excellent way to estimate how far you can see a target with a thermal imaging camera is to use a nomograph.
A nomograph is a graphical calculator which represents numerical relationships between variables such as focal length, range and the number of pixels on target.
