Explanation
Noise equivalent temperature difference. A measure of the
image noise level of an IR camera.
Undesired small disturbance in the infrared image
A set of values describing the circumstances under which
the measurement of an object was made, and the object itself
(such as emissivity, ambient temperature, distance etc.)
A non-calibrated value related to the amount of radiation
received by the camera from the object.
The set of colors used to display an IR image.
Stands for picture element. One single spot in an image.
Amount of energy emitted from an object per unit of time,
2
area and angle (W/m
Amount of energy emitted from an object per unit of time
(W)
The process by which electromagnetic energy, is emitted by
an object or a gas.
A piece of IR radiating equipment.
The current overall temperature measurement limitation of
an IR camera. Cameras can have several ranges. Expressed
as two blackbody temperatures that limit the current calibra-
tion.
A temperature which the ordinary measured values can be
compared with.
The amount of radiation reflected by an object relative to
the received radiation. A number between 0 and 1.
Percentage of water in the air, relative to what is physically
possible. Air temperature dependent.
The areas that contain temperatures outside the present
level/span settings are colored with the saturation colors.
The saturation colors contain an 'overflow' color and an 'un-
derflow' color.
There is also a third red saturation color that marks everything
saturated by the detector indicating that the range should
probably be changed.
