ABSTRACT
This chapter describes the measurable parameters that are used to portray and determine the performance of a complete thermal imager. To a certain extent the parameters of importance will be different for different applications, and the relevance of each measure of performance will be related to the type of application. The differences largely depend on whether the application is one where measuring temperature is of fundamental importance, or whether the application is in a surveillance role where the ability to detect and recognize objects at long ranges is the aim.
