9-3-2 Distance and Angle of Capture
Although distance usually does not affect the temperatures measured by the
software it can be helpful to know the distance to the target location. Generally,
the further away the IR sensor is from the target/background area, the less
thermal contrast seen in the image.
Angles of reflection can also affect the contrast. This is significant when the IR
sensor is operated at low angles over water there may be no perceived thermal
difference between the horizon and the water, i.e. the horizon can seem to
disappear. Users can change their angle by changing where they stand or by
attaching a camera to an unmanned aerial system.
While there is an input box for distance there is not an input for angle. Use the
text and voice annotation features of the device to create notes.
See Section 8-17-1-3 ROI Regional Environmental Parameters and Section 8-17-
2 Global Environmental Parameters to learn how to adjust the distance value of
an ROI.
9-3-3 Atmospheric Temperature
The imager has temperature compensation to correct environmental sources
of energy as this can affect the measurement results. Temperature readings
are especially altered when the emissivity of the object is low or the difference
between the object temperature and the ambient temperature is large. It
is necessary to compensate the results to eliminate the influence of the
environmental temperatures.
To get a more accurate temperature measurements set the atmospheric
temperature. Generally, atmospheric temperature is equal to ambient
temperature.
See Section 8-17-1-3 ROI Regional Environmental Parameters and Section
8-17-2 Global Environmental Parameters to learn how to adjust the atmospheric
temperature value of an ROI.
9-3-4 Reflected Temperature
Users can compensate for sources of energy reflected off objects being
measured to eliminate the influence of environmental temperatures. Often, the
reflected temperature is equivalent to the ambient temperature.
See Section 8-17-1-3 ROI Regional Environmental Parameters and Section
8-17-2 Global Environmental Parameters to learn how to adjust the reflected
temperature value of an ROI.
