absorption
(absorption
factor)
The amount of radiation absorbed by an object relative to the re-
ceived radiation. A number between 0 and 1.
atmosphere
The gases between the object being measured and the camera, nor-
mally air.
autoadjust
A function making a camera perform an internal image correction.
autopalette
The IR image is shown with an uneven spread of colors, displaying
cold objects as well as hot ones at the same time.
blackbody
Totally non-reflective object. All its radiation is due to its own
temperature.
blackbody
radiator
An IR radiating equipment with blackbody properties used to cali-
brate IR cameras.
calculated at-
mospheric
transmission
A transmission value computed from the temperature, the relative
humidity of air and the distance to the object.
cavity radiator
A bottle shaped radiator with an absorbing inside, viewed through
the bottleneck.
color
temperature
The temperature for which the color of a blackbody matches a spe-
cific color.
conduction
The process that makes heat diffuse into a material.
continuous
adjust
A function that adjusts the image. The function works all the time,
continuously adjusting brightness and contrast according to the im-
age content.
convection
Convection is a heat transfer mode where a fluid is brought into mo-
tion, either by gravity or another force, thereby transferring heat from
one place to another.
dual isotherm
An isotherm with two color bands, instead of one.
emissivity
(emissivity
factor)
The amount of radiation coming from an object, compared to that of
a blackbody. A number between 0 and 1.
emittance
Amount of energy emitted from an object per unit of time and area
(W/m
2
)
environment
Objects and gases that emit radiation towards the object being
measured.
estimated at-
mospheric
transmission
A transmission value, supplied by a user, replacing a calculated one
external optics
Extra lenses, filters, heat shields etc. that can be put between the
camera and the object being measured.
filter
A material transparent only to some of the infrared wavelengths.
FOV
Field of view: The horizontal angle that can be viewed through an IR
lens.
FPA
Focal plane array: A type of IR detector.
graybody
An object that emits a fixed fraction of the amount of energy of a
blackbody for each wavelength.
IFOV
Instantaneous field of view: A measure of the geometrical resolution
of an IR camera.
