5.11 Time Function Processing
The LWIR Web Server software contains a number of Time Function algorithms
which help deliver a more consistent temperature reading from a sometimes
noisy, changeable reading from the LWIR thermal imager.
The following sections help you choose and configure the time function most
appropriate for your application.
5.11.1 None
The Web Server will display the raw output from the LWIR thermal imaging
camera.
5.11.2 Averager
Refer to Fig. 4-2. The Averager time function can be used to ‘smooth’ the
temperature output signal in relation to the temperature input. The Averager
response can be adjusted to suit your application. With a fast response
speed, the temperature output signal tracks the input signal closely, any rapid
fluctuations in the input are reflected in the output. With a slow response
speed, the temperature output signal is much smoother, displaying more the
‘trend’ of the input signal rather than rapid changes.
