Identification Rating

Detection, Recognition, and Identification (DRI) are guidelines that have been set in place by The Night Vision Thermal Imaging Systems Performance Model, also referred to as the Johnson criteria. They are a universally accepted set of standards developed by the US Army to provide a means of measuring the distance whereby a thermal sensor can produce an image of a specific target.

Identification of an object means that you are able to differentiate between objects. For example, this person looks like a tall woman wearing a dress, that person looks like a soldier.

For a complete explanation of DRI measurements and what to expect from them, please see our Whitepaper on DRI: Thermal Distance Ratings Explained.
