FLIR i3 User Manual

ExplanationTerm or expression
Extra lenses, filters, heat shields etc. that can be put between
the camera and the object being measured.
external optics
A material transparent only to some of the infrared wavelengths.filter
Field of view: The horizontal angle that can be viewed through
an IR lens.
FOV
Focal plane array: A type of IR detector.FPA
An object that emits a fixed fraction of the amount of energy of
a blackbody for each wavelength.
graybody
Instantaneous field of view: A measure of the geometrical reso-
lution of an IR camera.
IFOV
A way of compensating for sensitivity differences in various parts
of live images and also of stabilizing the camera.
image correction (internal or external)
Non-visible radiation, having a wavelength from about 2–13 μm.infrared
infraredIR
A function highlighting those parts of an image that fall above,
below or between one or more temperature intervals.
isotherm
A bottle-shaped radiator with a uniform temperature viewed
through the bottleneck.
isothermal cavity
An electrically powered light source on the camera that emits
laser radiation in a thin, concentrated beam to point at certain
parts of the object in front of the camera.
Laser LocatIR
An electrically powered light source on the camera that emits
laser radiation in a thin, concentrated beam to point at certain
parts of the object in front of the camera.
laser pointer
The center value of the temperature scale, usually expressed
as a signal value.
level
A way to adjust the image by manually changing certain param-
eters.
manual adjust
Noise equivalent temperature difference. A measure of the image
noise level of an IR camera.
NETD
Undesired small disturbance in the infrared imagenoise
A set of values describing the circumstances under which the
measurement of an object was made, and the object itself (such
as emissivity, reflected apparent temperature, distance etc.)
object parameters
A non-calibrated value related to the amount of radiation re-
ceived by the camera from the object.
