5. Techniques of Infrared

rmometer

The

5.1 Field of View (FOV) ratio

Distance to Diameter (DS) ratio

The field of view is the angle of vision at which the

instrument operates , and is determined by the optics

of the unit. The FOV is the ratio of the distance from the

target to the target diameter. The smaller the target , the

closer you should be to it . When the target diameter is

small, it is important to bring the thermome ter closer to the

target to insure t hat only the target i s measured,e xcluding

the surroundings.
